Abstract
The first-cured tobacco contains macromolecular substances with negative impacts on tobacco products quality, and must be aged and fermented to mitigate their effects on the tobacco products quality. However, the natural fermentation takes a longer cycle with large coverage area and low economic efficiency. Microbial fermentation is a method to improve tobacco quality. The change of chemical composition of tobacco during the fermentation is often correlated with shapes of tobacco. This study aimed to investigate the effects of tobacco microorganisms on the quality of different shapes of tobacco. Specifically, Bacillus subtilis B1 and Cytobacillus oceanisediminis C4 with high protease, amylase, and cellulase were isolated from the first-cured tobacco, followed by using them for solid-state fermentation of tobacco powder (TP) and tobacco leaves (TL). Results showed that strains B1 and C4 could significantly improve the sensory quality of TP, enabling it to outperform TL in overall texture and skeleton of tobacco products during cigarette smoking. Compared with the control, microbial fermentation could increase reducing sugar; regulate protein, starch, and cellulose, reduce nicotine, improve total aroma substances, and enable the surface of fermented TP and TL to be more loose, wrinkled, and porous. Microbial community analysis indicated that strains B1 and C4 could change the native structure of microbial community in TP and TL. LEfSe analysis revealed that the potential key biomarkers in TP and TL were Bacilli, Pseudonocardia, Pantoea, and Jeotgalicoccus, which may have cooperative effects with other microbial taxa in improving tobacco quality. This study provides a theoretical basis for improving tobacco fermentation process for better cigarettes quality.

Nabil-Adam A, Ashour ML, Shreadah MA. The hepatoprotective candidates by synergistic formula of marine and terrestrial against Acetaminophen toxicity using in-vitro, in-vivo, and in silico screening approach. Saudi J Biol Sci 2023; 30:103607. [PMID: 36941882 PMCID: PMC10023929 DOI: 10.1016/j.sjbs.2023.103607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/27/2023] [Accepted: 02/19/2023] [Indexed: 02/26/2023] Open
Abstract
Background One of the most regularly used hepatotoxic medicines is paracetamol (acetaminophen, N-acetyl-p-aminophenol; APAP). It causes liver failure in overdoses but is safe at therapeutic dosages. Combination therapy combining many natural compounds with a synergistic impact as hepatoprotective agents has become an essential therapeutic method against various disorders. Objective Due to the lack of literature on paracetamol's effects on hematological and hepatic status parameters in male albino mice, the main goal of this study was to compare the hepatoprotective activities of a mixture of three marine-derived polyphenolics and polysaccharides (Sargassum vulgare Bacillus oceanisediminis, and alginic acids) to Chrysanthemum extract and the mixture of them. Methods Sargassumvulgare, Bacillus Oceanisediminis, and alginate, as well as Chrysanthemum ethanol extracts, were tested for APAP-induced liver damage. Group 1 received saline solution subcutaneously, while Group 2 received 500 mg/kg body weight/day APAP intraperitoneal. Group 3 got 200 mg/day algal extract i.p. As in group 3, group 4 got an i.p. dose of 200 mg of algal extract before the APAP dose. This group was protected by Sargassum vulgare extract. Group 5: Received 200 mg/100 g/body of Bacillus oceanisediminis extracts i.p. for one week. Group 6: Received 200 mg/body of Bacillus oceanisediminis extract i.p. for one week before APAP treatment. Alginate (p200 mg/body weight/day) was given to Group 7. As in group 7, group 8 received 200 mg/body weight/day alginate extract i.p. before APAP. Group 9: Chrysanthemum extracts 200 mg/day for a week. Group 10: got an i.p. dose of Chrysanthemum extracts for one week before the APAP dose. Group 11: Four mixed extracts (Bacillus Oceanisediminis, Sargassum vulgare, Chrysanthemum, and alginate) were i.p200 mg/day for one week as a positive (+ve) control group. Group 12: Received i.p200 mg/kg combination extract for one week before APAP. Results Due to their synergistic antioxidant and anti-inflammatory actions, marine extracts and combinations of marine-derived extracts demonstrated a great effect against APAP toxicity, demonstrating hepatoprotective potential against APAP-induced liver damage. Conclusion The synergy of the three marine-derived combinations may lead to novel liver toxicity prevention agents.

Abstract
A Gram-stain-positive, rod-shaped and motile strain, designated FJAT-49705T, was isolated from the citrus rhizosphere soil sample. Strain FJAT-49705T grew at 20-40 °C (optimum, 30 °C) and pH 6.0-11.0 (optimum, pH 7.0) with 0-5 % (w/v) NaCl (optimum, 2 %). Strain FJAT-49705T showed high 16S rRNA gene sequence similarity to 'Bacillus dafuensis' FJAT-25496T (99.7 %) and Cytobacillus solani FJAT-18043T (98.0 %). In phylogenetic (based on 16S rRNA gene sequences) and phylogenomic trees (based on 71 bacterial single-copy genes), strain FJAT-49705T clustered with the members of the genus Cytobacillus. MK-7 was the only isoprenoid quinone present. The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The genomic DNA G+C content was 36.9 %. The average nucleotide identity (ANI) values between FJAT-49705T and 'B. dafuensis' FJAT-25496T and C. solani FJAT-18043T were below the cut-off level (95-96 %) recommended as the ANI criterion for interspecies identity. Based on the above results, strain FJAT-49705T represents a novel species of the genus Cytobacillus, for which the name Cytobacillus citreus sp. nov. is proposed. The type strain is FJAT-49705T (=CCTCC AB 2019243T= LMG 31580T).

Cytobacillus pseudoceanisediminis sp. nov., A Novel Facultative Methylotrophic Bacterium with High Heavy Metal Resistance Isolated from the Deep Underground Saline Spring. Curr Microbiol 2022; 80:31. [PMID: 36478127 DOI: 10.1007/s00284-022-03141-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022]
Abstract
In this study, we present the characterization of the BNO1T bacterial strain isolated from the deep subsurface saline spring at the Baksan Neutrino Observatory INR RAS (Kabardino-Balkaria, Russia). The complete genome sequence of the strain BNO1T is 5,347,902 bp, with a GC content 41 and 49%. The cell wall peptidoglycan contains meso-diaminopimelic acid. The major isoprenoid quinone is MK-7 and the polar lipids are diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The major fatty acids are anteiso-C15:0 (23.34%), iso-C15:0 (20.10%), C16:0 (11.96%), iso-C16:0 (10.88%), and anteiso-C17:0 (10.79%). The 16S rRNA gene sequence clearly demarcated the strain as belonging to Cytobacillus genera. Based on the phylogenetic analysis, ANI (average nucleotide identity) and dDDH (digital DNA-DNA hybridization) assessments we propose to assign the strain BNO1T and other related strains to new species and to name it Cytobacillus pseudoceanisediminis sp. nov. (The values of ANI and dDDH between BNO1T and Cytobacillus oceanisediminis CGMCC 1.10115 T are 80.65% and 24.7%, respectively; values of ANI and dDDH between BNO1T and Cytobacillus firmus NCTC 10335 T are 89% and 38%, respectively). Genomic analysis of strain BNO1T revealed pathways for C1 compounds oxidation and two pathways for C1 compounds assimilation: serine and ribulose monophosphate pathways. In addition, strain BNO1T contains a plasmid (342,541 bp) coding multiple genes involved in heavy metal ion balance. Moreover, heavy metal toxicity testing confirmed the high potential of the strain BNO1T as a source of metal resistance genes and enzymes. The type strain is BNO1T (= BIM B-1921 T = VKM B-3664 T).

Abstract
Systemic characterization of the human gut microbiota highlighted its vast therapeutic potential. Despite having enormous potential, the non-availability of their culture representatives created a bottleneck to understand the concept of microbiome-based therapeutics. The present study is aimed to isolate and evaluate the probiotic potential of a human gut isolate. Physiochemical, morphological, and phylogenetic characterization of a human gut isolate identifies it as a rod-shaped gram-negative microbe taxonomically affiliated with the Cytobacillus genus, having an optimal growth at 37°C in a partially alkaline environment (pH 8.0). This human gut isolate showed continuous growth in the presence of salts (up to 7% NaCl and 10% KCl), antibiotics, metals and metalloids [silver nitrate (up to 2 mM); lead acetate (up to 2 mM); sodium arsenate (up to 10 mM); potassium dichromate (up to 2 mM)], gastric and intestinal conditions, diverse temperature (25–50°C), and pH (5–9) conditions making it fit to survive in the highly variable gut environment. Genomic characterization identified the presence of gene clusters for diverse bio-catalytic activity, stress response, and antimicrobial activity, as well as it indicated the absence of pathogenic gene islands. A combination of functional features like anti-amylase, anti-lipase, glutenase, prolyl endopeptidase, lactase, bile salt hydrolase, cholesterol oxidase, and anti-pathogenic activity is indicative of its probiotic potential in various disorders. This was further substantiated by the CaCo-2 cell line assay confirming its cellular adherence and biosafety. Conclusively, human gut isolate possessed significant probiotic potential that can be used to promote animal and human health.

Abstract
The Nostoc sp. strain CCCryo 231-06 is a cyanobacterial strain capable of surviving under extreme conditions and thus is of great interest for the astrobiology community. The knowledge of its complete genome sequence would serve as a guide for further studies. However, a major concern has been placed on the effects of contamination on the quality of sequencing data without a reference genome. Here, we report the use of microfluidic technology combined with single cell sequencing and de novo assembly to minimize the contamination and recover the complete genome of the Nostoc strain CCCryo 231-06 with high quality. 100% of the whole genome was recovered with all contaminants removed and a strongly supported phylogenetic tree. The data reported can be useful for comparative genomics for phylogenetic and taxonomic studies. The method used in this work can be applied to studies that require high-quality assemblies of genomes of unknown microorganisms. This work uses a microfluidic platform for Nostoc single cell sequencing This technology provides minimal contamination in single cell sequencing Complete genome of the Nostoc strain CCCryo 231-06 was recovered with high quality

Abstract
Although the microbiome of blood-feeding insects serves an integral role in host physiology, both beneficial and pathogenic, little is known of the microbial community of black flies. An investigation, therefore, was undertaken to identify culturable bacteria from one of Malaysia's most common black flies, Simulium tani Takaoka and Davies, using 16S rDNA sequencing, and then evaluate the isolates for antibiotic resistance and virulence genes. A total of 20 isolates representing 11 bacterial species in four genera were found. Five isolates showed β-hemolysis on Columbia agar, and virulence genes were found in three of these isolates. Some degree of resistance to six of the 12 tested antibiotics was found among the isolates. The baseline data from this study suggest rich opportunities for comparative studies exploring the diversity and roles of the microbiome of S. tani and other Southeast Asian black flies.

Abstract
Bioaerosols are defined as aerosols that comprise particles of biological origin or activity that may affect living organisms through infectivity, allergenicity, toxicity, or through pharmacological or other processes. Interest in bioaerosol exposure has increased over the last few decades. Exposure to bioaerosols may cause three major problems in the food industry, namely: (i) contamination of food (spoilage); (ii) allergic reactions in individual consumers; or (iii) infection by means of pathogenic microorganisms present in the aerosol. The aim of this study was to characterise the culturable fraction of bioaerosols in the production environment of a fruit juice manufacturing facility and categorise isolates as harmful, innocuous or potentially beneficial to the industry, personnel and environment. Active sampling was used to collect representative samples of five areas in the facility during peak and off-peak seasons. Areas included the entrance, preparation and mixing area, between production lines, bottle dispersion and filling stations. Microbes were isolated and identified using 16S, 26S or ITS amplicon sequencing. High microbial counts and species diversity were detected in the facility. 239 bacteria, 41 yeasts and 43 moulds were isolated from the air in the production environment. Isolates were categorised into three main groups, namely 27 innocuous, 26 useful and 39 harmful bioaerosols. Harmful bioaerosols belonging to the genera Staphylococcus, Pseudomonas, Penicillium and Candida were present. Although innocuous and useful bioaerosols do not negatively influence human health their presence act as an indicator that an ideal environment exists for possible harmful bioaerosols to emerge.

Abstract
Background and Aim Bacillus species are widely distributed microorganisms in nature that are responsible for outbreaks of food poisoning and a common cause of food spoilage. This study aimed to isolate and identify foodborne Bacillus species from meat and to determine the antimicrobial activities of commercial essential oils and spices powder extracted from certain medicinal plants. Methods Sixty meat samples were collected in Assiut city and subdivided into raw meat and processed meat. Bacillus spp were isolated and identified according to their cultural characters, biochemical reactions, serological typing, and 16S rRNA gene sequencing. The antibacterial activity of essential oils and spices powder was measured by using well-diffusion and microbial count techniques. Results The prevalence of Bacillus spp. in the examined raw meat samples and processed meat samples was 13.34%, and 26.67%, respectively. There was a marked decrease in the total Bacillus species count after treatment of minced beef with essential oils and spices powder compared to the untreated one. Black seed oil was the most potent antibacterial essential oil among the tested oils present in this study. Conclusion Essential oils and spices powder of certain medicinal plants (cumin: Cuminum cyminum, black seeds: Nigella sativa, cloves: Syzygium aromaicum, cinnamon: Cinnamomum zeylanicum, and Marjoram: Origanum majorana) have a potential in vitro antimicrobial activity against Bacillus spp. Furthermore, Nigella sativa oil exhibited the most potent antibacterial activity against Bacillus spp.

Abstract
P59, a virulent phage of Bacillus oceanisediminis, was isolated from the sediment of Weiming Lake at Peking University (Beijing, China). P59 showed the typical morphology of myovirids. The complete genome sequence of P59 is 159,363 bp in length with a G+C content of 42.34%. The genome sequence has very low similarity to the other phage genome sequences in the GenBank database, suggesting that P59 is a new phage. A total of 261 open reading frames and 15 tRNA genes were predicted. Based on its morphological and genetic traits, we propose phage P59 to be a new member of the family Herelleviridae.

Abstract
BACKGROUND Root-knot nematodes (Meloidogyne spp.) are soilborne pathogens that can cause great damage to and economic loss of crops globally. Owing to the high toxicity of chemicals toward humans and the environment, the use of biocontrol bacteria, a promising method for controlling root-knot nematodes, has gained attention. RESULTS To screen novel bacterial strains for their ability to control root-knot nematodes, 106 bacterial strains were isolated from soil. Eight of the obtained isolates exhibited satisfactory nematicidal activity against Meloidogyne incognita at 2-fold dilutions (approximately 3 × 1012 CFU mL-1 ) after 12 h of exposure. Based on their physiological, biochemical and molecular (16S rRNA and gyrB gene sequences) characteristics, the eight strains were identified as Bacillus halotolerans, B. kochii, B. oceanisediminis, B. pumilus, B. toyonensis, B. cereus, Pseudomonas aeruginosa and B. pseudomycoides. In greenhouse and field experiments, the eight isolates suppressed M. incognita up to 69.96% compared to the control. Additionally, the yield of tomato increased 1.4-26.1% over that of the control. CONCLUSION The strains of B. halotolerans DDWA, B. kochii DDWB, B. oceanisediminis DDWC and B. pseudomycoides JNC have potential to control M. incognita, which has not been previously reported. © 2020 Society of Chemical Industry.

Abstract
The genus Bacillus, harbouring 293 species/subspecies, constitutes a phylogenetically incoherent group. In the absence of reliable means for grouping known Bacillus species into distinct clades, restricting the placement of new species into this genus has proven difficult. To clarify the evolutionary relationships among Bacillus species, 352 available genome sequences from the family Bacillaceae were used to perform comprehensive phylogenomic and comparative genomic analyses. Four phylogenetic trees were reconstructed based on multiple datasets of proteins including 1172 core Bacillaceae proteins, 87 proteins conserved within the phylum Firmicutes, GyrA-GyrB-RpoB-RpoC proteins, and UvrD-PolA proteins. All trees exhibited nearly identical branching of Bacillus species and consistently displayed six novel monophyletic clades encompassing 5-23 Bacillus species (denoted as the Simplex, Firmus, Jeotgali, Niacini, Fastidiosus and Alcalophilus clades), interspersed with other Bacillaceae species. Species from these clades also generally grouped together in 16S rRNA gene trees. In parallel, our comparative genomic analyses of Bacillus species led to the identification of 36 molecular markers comprising conserved signature indels in protein sequences that are specifically shared by the species from these six observed clades, thus reliably demarcating these clades based on multiple molecular synapomorphies. Based on the strong evidence from multiple lines of investigations supporting the existence of these six distinct 'Bacillus' clades, we propose the transfer of species from these clades into six novel Bacillaceae genera viz. Peribacillus gen. nov., Cytobacillus gen. nov., Mesobacillus gen. nov., Neobacillus gen. nov., Metabacillus gen. nov. and Alkalihalobacillus gen. nov. These results represent an important step towards clarifying the phylogeny/taxonomy of the genus Bacillus.

Abstract
Groundwater samples were collected from the tubular wells of a groundwater heat pump (GWHP), and the psychrophilic, mesophilic, and thermophilic bacteria inhabiting the collected groundwater were cultured and isolated. Using the isolated bacteria, we analyzed temperature-dependent changes in autochthonous bacteria based on the operation of the GWHP. Microbial culture identified eight species of bacteria: five species of thermophilic bacteria (Anoxybacillus tepidamans, Bacillus oceanisediminis, Deinococcus geothermalis, Effusibacillus pohliae, and Vulcaniibacterium thermophilum), one species of mesophilic bacteria (Lysobacter mobilis), and two species of psychrophilic bacteria (Paenibacillus elgii and Paenibacillus lautus). The results indicated A. tepidamans as the most dominant thermophilic bacterium in the study area. Notably, the Anoxybacillus genus was previous reported as a microorganism capable of creating deposits that clog above-ground wells and filters at geothermal power plants. Additionally, we found that on-site operation of the GWHP had a greater influence on the activity of thermophilic bacteria than on psychrophilic bacteria among autochthonous bacteria. These findings suggested that study of cultures of thermophilic bacteria might contribute to understanding the bio-clogging phenomena mediated by A. tepidamans in regard to GWHP-related thermal efficiency.

Abstract
Here we inspect whether microbial life may disperse using dust transported by wind in the Atacama Desert in northern Chile, a well-known Mars analog model. By setting a simple experiment across the hyperarid core of the Atacama we found that a number of viable bacteria and fungi are in fact able to traverse the driest and most UV irradiated desert on Earth unscathed using wind-transported dust, particularly in the later afternoon hours. This finding suggests that microbial life on Mars, extant or past, may have similarly benefited from aeolian transport to move across the planet and find suitable habitats to thrive and evolve.

Abstract
A novel Gram-stain-positive, catalase- and oxidase-positive, endospore-forming bacterium, designated GY 10110T, was isolated from mangrove soil collected from Qinzhou, Guangxi province, China. Cells were aerobic, motile with peritrichous flagella and rod-shaped. The strain grew at 15-37 °C (optimum, 28 °C), at 0-3 %(w/v) NaCl (1 %) and at pH 6.0-9.0 (pH 7.0). The major fatty acids of strain GY 10110T were anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0. The predominant menaquinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The polar lipid profile comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphoglycolipid, glycolipid, two unidentified aminophospholipids and three unidentified phospholipids. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain GY 10110T was closely related to Falsibacillus pallidus CCTCC AB 207188T (98.0 % sequence similarity) and Bacillus oceanisediminis CGMCC 1.10115T (96.9 %), respectively. The G+C content of strain GY 10110T based on the whole genome sequence was 42.3 mol%. The novel strain showed an average nucleotide identity (ANI) value of 77.8 % and a digital DNA-DNA hybridization (dDDH) value of 15.6 % with Falsibacillus pallidus CCTCC AB 207188T based on draft genome sequences, followed by Bacillus oceanisediminis CGMCC 1.10115T with ANI and dDDH values of 75.2 and 12.8 %, respectively. The results of the polyphasic taxonomic study, including phenotypic, chemotaxonomic and phylogenetic analysis, showed that strain GY 10110T represents a novel species of the genus Falsibacillus, for which the name Falsibacillus albus sp. nov. is proposed. The type strain is GY 10110T (=CGMCC 1.13648T=NBRC 113502T).

Abstract
A Gram-stain-positive, motile, rod-shaped bacterial strain, YN-1T, was isolated from a rice field in the town of Jietou, Yunnan Province, PR China. Colonies were circular, 1-2 mm in diameter, creamy white, with slightly irregular margins. The isolate grew optimally at 37 °C, pH 7.0 and with 1.0 % (w/v) NaCl. On the basis of the results of 16S rRNA gene sequence similarity comparisons, YN-1T clustered together with other species of the genus Bacillus and showed highest similarities with Bacillus onubensis 0911MAR22V3T (98.0 %), Bacillus humi LMG22167T (97.5 %), 'Bacillus timonensis' 10403023 (97.4 %) and 'Bacillussinesaloumensis' P3516 (97.1 %). However, the DNA-DNA hybridization values between YN-1T and closely related strains of species of the genus Bacillus were well below 47 %, indicating that they represent different taxa. The average nucleotide identity and the Genome-to-Genome Distance Calculator also revealed low relatedness (below 95 and 70 %, respectively) between YN-1T and type strains of closely related species of the genus Bacillus. The DNA G+C content of the strain was 40 mol%. The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, and C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, three unidentified aminophospholipids and two other unidentified lipids. Physiological and biochemical test results were also different from those of the most closely related species. On the basis of the phenotypic, genetic and chemotaxonomic data, strain YN-1T is considered to represent a novel species of the genus Bacillus, for which the name Bacillusaciditolerans sp. nov. is proposed, with strain YN-1T (=CCTCC AB 2017280T=JCM 32973T) as the type strain.

Abstract
Submarine hydrothermal vents are inhabited by a variety of microorganisms capable of tolerating environmental extremes, making them ideal candidates to further expand our knowledge of the limitations for terrestrial life, including their ability to survive the exposure of spaceflight-relevant conditions. The spore resistance of two Bacillus spp. strains, APA and SBP3, isolated from two shallow vents off Panarea Island (Aeolian Islands, Italy), to artificial and environmental stressors (i.e., UVC radiation, X-rays, heat, space vacuum, hydrogen peroxide [H2O2], and low-pressure plasma), was compared with that of two close phylogenetic relatives (Bacillus horneckiae and Bacillus oceanisediminis). Additional comparisons were made with Bacillus sp. isolated from spacecraft assembly facilities (B. horneckiae, Bacillus pumilus SAFR-032, and Bacillus nealsonii) and the biodosimetry strain and space microbiology model organism Bacillus subtilis. Overall, a high degree of spore resistance to stressors was observed for the strains isolated from spacecraft assembly facilities, with an exceptional level of resistance seen by B. pumilus SAFR-032. The environmental isolate SBP3 showed a more robust spore resistance to UVC, X-rays, H2O2, dry heat, and space vacuum than the closely related B. horneckiae. Both strains (SBP3 and APA) were more thermotolerant than their relatives, B. horneckiae and B. oceanisediminis, respectively. SBP3 may have a novel use as a bacterial model organism for future interrogations into the potential of forward contamination in extraterrestrial environments (e.g., icy moons of Jupiter or Saturn), spacecraft sterilization and, broadly, microbial responses to spaceflight-relevant environmental stressors.

Abstract
A Gram-reaction-positive, strictly aerobic, motile, endospore- forming, and rod-shaped bacterial strain designated 135PIL107-10T was isolated from a sponge on Jeju Island, and its taxonomic position was investigated using a polyphasic approach. Strain 135PIL107-10T grew at 20-37°C (optimum temperature, 25°C) and pH 6.0-10.0 (optimum pH, 6.0) on marine and R2A agars. Based on 16S rRNA gene phylogeny analysis, the novel strain formed a new branch within the genus Bacillus of the family Bacillaceae, and formed clusters with Bacillus thaohiensis NHI-38T (96.8%), Bacillus fengqiuensis NPK15T (96.7%), and Bacillus songklensis CAU 1033T (96.7%). Lower sequence similarities (97.0%) were found with the type strains of all other recognized members of the genus Bacillus (95.6-96.8% similarity). The G + C content of the genomic DNA was 43.6 mol%. The predominant respiratory quinone was menaquinone-7 and the major fatty acids were iso-C15:0 and iso-C17:1ω10c. The overall polar lipid patterns were diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The isolate therefore represents a novel species, for which the name Bacillus spongiae sp. nov. is proposed, with the type strain 135PIL107-10T (= KACC 19275T = LMG 30080T).

Abstract
A novel Gram-stain-positive, motile and facultatively anaerobic strain, designated NC2-31T, was isolated from sediment from the coast of Weihai, PR China. Optimal growth occurred at 37 °C, pH 7.5 and with 2.0-3.0 % (w/v) NaCl. MK-7 was the major respiratory quinone. Meso-diaminopimelic acid was a diagnostic diamino acid in the peptidoglycan. The major polar lipids of NC2-31T were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). The genomic DNA G+C content of the strain was 46.3 mol%. The predominant cellular fatty acids (>10.0 %) of NC2-31T were iso-C15 : 0 (18.9 %), anteiso-C15 : 0 (15.8 %), summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) (15.3 %) and iso-C16 : 0 (10.3 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that NC2-31T should be classified as representing a member of the genus Bacillus. Based on data from the current polyphasic study, NC2-31T represents a novel species within the genus Bacillus, for which the name Bacillusmarinisedimentorum sp. nov. is proposed with type strain NC2-31T (=KCTC 33721T=MCCC 1K01239T).

Abstract
A novel bacterial strain S36T was isolated from the deep-sea sediment collected from Pacmanus hydrothermal field, Manus Basin. The strain was Gram-stain-positive, aerobic, rod-shaped, endospore-forming, and motile. It was able to grow at 16-50 °C, pH 6.0-10.0, and in the presence of 0-11 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain S36T was a member of genus Bacillus and shares the highest sequence identity with Bacillus herbersteinensis D-1,5aT (97.0 %). The value of DNA-DNA hybridization between strain S36T and B. herbersteinensis D-1,5aT was 22.8 %. The cell wall diagnostic diamino acid of strain S36T was meso-diaminopimelic acid and the polar lipid profile of strain S36T contained diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The predominant respiratory quinine was MK-7. The major cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The genomic DNA G+C content of strain S36T was 43.0 mol%. On the basis of phylogenetic analysis, DNA-DNA hybridization, and phenotypic characteristics, it was concluded that strain S36T represents a novel species of the genus Bacillus, for which the name Bacillus iocasae sp. nov. was proposed. The type strain is S36T (=KCTC 33864T=DSM 104297T=CGMCC 1.16030T).

Biochemical properties of a new thermo- and solvent-stable xylanase recovered using three phase partitioning from the extract of Bacillus oceanisediminis strain SJ3. BIORESOUR BIOPROCESS 2017; 4:29. [PMID: 28736694 PMCID: PMC5498614 DOI: 10.1186/s40643-017-0161-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Accepted: 07/01/2017] [Indexed: 11/29/2022] Open
Abstract
The present study investigates the production and partial biochemical characterization of an extracellular thermostable xylanase from the Bacillus oceanisediminis strain SJ3 newly recovered from Algerian soil using three phase partitioning (TPP). The maximum xylanase activity recorded after 2 days of incubation at 37 °C was 20.24 U/ml in the presence of oat spelt xylan. The results indicated that the enzyme recovered in the middle phase of TPP system using the optimum parameters were determined as 50% ammonium sulfate saturation with 1.0:1.5 ratio of crude extract: t-butanol at pH and temperature of 8.0 and 10 °C, respectively. The xylanase was recovered with 3.48 purification fold and 107% activity recovery. The enzyme was optimally active at pH 7.0 and was stable over a broad pH range of 5.0–10. The optimum temperature for xylanase activity was 55 °C and the half-life time at this temperature was of 6 h. At this time point the enzyme retained 50% of its activity after incubation for 2 h at 95 °C. The crude enzyme resist to sodium dodecyl sulfate and β-mercaptoethanol, while all the tested ions do not affect the activity of the enzyme. The recovered enzyme is, at least, stable in tested organic solvents except in propanol where a reduction of 46.5% was observed. Further, the stability of the xylanase was higher in hydrophobic solvents where a maximum stability was observed with cyclohexane. These properties make this enzyme to be highly thermostable and may be suggested as a potential candidate for application in some industrial processes. To the best of our knowledge, this is the first report of xylanase activity and recoverey using three phase partitioning from B. oceanisediminis.

Abstract
A halotolerant, Gram-positive bacterium (strain NE-14T), which was isolated from sediment samples of the South China Sea, was subjected to a taxonomic study. Strain NE-14T grew well at wide temperature and pH ranges, 10.0-45.0 °C and pH 6-10, with an optimum at 30 °C and pH 8.0, respectively. Growth of strain NE-14T was observed at total salt concentrations of 0-10 % (w/v) with optimum at 2 % (w/v). Phylogenetic analysis based on 16S rRNA gene sequence comparison indicated that the isolate belongs to the genus Bacillus. Strain NE-14T was related most closely to Bacillus shackletonii LMG 18435T, Bacillus bataviensis LMG 21833T, Bacillus idriensis SMC 4352-2T and Bacillus drentensis LMG 21831T with 16S rRNA gene sequence similarities of 96.2, 95.9, 95.8 and 95.7 %, respectively. DNA-DNA hybridization between strain NE-14T and B. shackletonii LMG 18435T, B. bataviensis LMG 21833T, B. idriensis SMC 4352-2T and B. drentensis LMG 21831T gave reassociation values of about 27.4, 22.4, 16.4 and 15.9 %, respectively. The DNA G+C content of strain NE-14T was 39.2 mol%. The predominant isoprenoid quinone was menaquinone 7 (MK-7). The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant cellular fatty acids of strain NE-14T were iso-C15 : 0 and anteiso-C15 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phospholipid. Based on the phenotypic and phylogenetic characteristics, it is proposed that strain NE-14T be classified as representing a novel species of the genus Bacillus, for which the name Bacillus ectoiniformans sp. nov. is proposed. The type strain is NE-14T ( = DSM 28970T = JCM 30397T).

Abstract
A Gram-stain-positive, endospore-forming rod (designated strain CC-LY275T) was isolated from a pesticide wastewater sample. The isolate grew at a temperature 20-45 °C, at pH 7.0-8.0 and tolerated NaCl 6 % (w/v). The most closely related strains in terms of 16S rRNA gene sequence similarity were Bacillus horneckiae (97.1 %) and Bacillus oceanisediminis (96.8 %), respectively. The G+C content of the genomic DNA was 37.9 mol%. Strain CC-LY275T was determined to possess iso-C14 : 0, iso-C15 : 0 and anteiso-C15 : 0 as predominant fatty acids. The major polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Cell-wall peptidoglycan contained meso-diaminopimelic acid; menaquinone (MK-7) was the predominant respiratory quinone. According to the distinct phylogenetic, phenotypic and chemotaxonomic properties, the name Bacillus formosensis sp. nov. (type strain CC-LY275T = BCRC 80443T = JCM 18448T) is proposed.

Cell-wall amino acids were l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. The genomic DNA G+C content of strains JC247T and JC248 was 48.2 and 48.1 mol%, respectively. Both strains were closely related with mean DNA–DNA hybridization >90 %. 16S rRNA gene sequence analysis of both strains indicated that they are members of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes. Both strains had a 16S rRNA gene sequence similarity of 96.93 % with Bacillus firmus NCIMB 9366T and < 96.92 % with other members of the genus Bacillus. Sequence similarity between strain JC247T and JC248 was 100 %. Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strains JC247T and JC248 as representatives of a novel species of the genus Bacillus, for which the name Bacillus
crescens sp. nov. is proposed. The type strain is JC247T ( = KCTC 33627T = LMG 28608T).

Abstract
A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium (FJAT-14571T) was isolated from a soil sample in Taiwan. Strain FJAT-14571T grew at 20–40 °C (optimum 35 °C), pH 6–10 (optimum pH 8) and 0–2 % (w/v) NaCl (optimum 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain FJAT-14571T was a member of the genus Bacillus and was most closely related to Bacillus oceanisediminis DSM 24771T (96.2 %). DNA–DNA relatedness between strain FJAT-14571T and B. oceanisediminis DSM 24771T was low (32.0 % ± 0.88 %). The diagnostic diamino acid of the peptidoglycan of strain FJAT-14571T was meso-diaminopimelic acid and the predominant menaquinone was MK-7 (96.6 %). The major cellular fatty acids were iso-C15 : 0 (46.4 %), anteiso-C15 : 0 (7.6 %), iso-C17 : 0 (8.2 %) and iso-C16 : 0 (10.0 %) and the DNA G+C content was 40.8 mol%. Phenotypic, chemotaxonomic and genotypic properties clearly indicated that strain FJAT-14571T represents a novel species within the genus Bacillus, for which the name Bacillus taiwanensis sp. nov. is proposed. The type strain is FJAT-14571T ( = DSM 27845T = CGMCC1.1 2698T).

Abstract
A novel Gram-stain-positive, motile, catalase- and oxidase-positive, endospore-forming, facultatively anaerobic rod, designated strain JSM 100118(T), was isolated from an oyster (Crassostrea hongkongensis) collected from the tidal flat of Naozhou Island in the South China Sea. Strain JSM 100118(T) was able to grow with 0-13% (w/v) NaCl (optimum 2-5%), at pH 5.5-10.0 (optimum pH 7.5) and at 5-50 °C (optimum 30-35 °C). The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant respiratory quinone was menaquinone-7 and the major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, C16 : 0 and C16 : 1ω11c. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unknown glycolipid and an unknown phospholipid. The genomic DNA G+C content was 35.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 100118(T) belonged to the genus Bacillus , and was most closely related to Bacillus litoralis SW-211(T) (98.9% 16S rRNA gene sequence similarity), Bacillus halosaccharovorans E33(T) (98.3%), Bacillus niabensis 4T19(T) (97.8%) and Bacillus herbersteinensis D-1,5a(T) (97.1%). The combination of results from the phylogenetic analysis, DNA-DNA hybridization, and phenotypic and chemotaxonomic characterization supported the conclusion that strain JSM 100118(T) represents a novel species of the genus Bacillus , for which the name Bacillus crassostreae sp. nov. is proposed. The type strain is JSM 100118(T) ( = CTCC AB 2010452(T) =DSM 24486(T) =JCM 17523(T)).

Bacillus dabaoshanensis sp. nov., a Cr(VI)-tolerant bacterium isolated from heavy-metal-contaminated soil. Arch Microbiol 2015; 197:513-20. [PMID: 25603996 DOI: 10.1007/s00203-015-1082-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2014] [Revised: 01/03/2015] [Accepted: 01/10/2015] [Indexed: 10/24/2022]
Abstract
A Cr(VI)-tolerant, Gram-staining-positive, rod-shaped, endospore-forming and facultative anaerobic bacterium, designated as GSS04(T), was isolated from a heavy-metal-contaminated soil. Strain GSS04(T) was Cr(VI)-tolerant with a minimum inhibitory concentration of 600 mg l(-1) and was capable of reducing Cr(VI) under both aerobic and anaerobic conditions. Growth occurred with presence of 0-3 % (w/v) NaCl (optimum 1 %), at pH 5.5-10.0 (optimum pH 7.0) and 15-50 °C (optimum 30-37 °C). The main respiratory quinone was MK-7 and the major fatty acids were anteiso-C15:0 and iso-C15:0. The DNA G+C content was 41.1 mol%. The predominant polar lipid was diphosphatidylglycerol. Based on 16S rRNA gene sequence similarity, the closest phylogenetic relative was Bacillus shackletonii DSM 18868(T) (97.6 %). The DNA-DNA hybridization between GSS04(T) and its closest relatives revealed low relatedness (<70 %). The results of phenotypic, chemotaxonomic and genotypic analyses clearly indicated that strain GSS04(T) represents a novel species of the genus Bacillus, for which the name Bacillus dabaoshanensis sp. nov. is proposed. The type strain is GSS04(T) (=CCTCC AB 2013260(T) = KCTC 33191(T)).

Abstract
A Gram-stain-positive, short rod-shaped and motile, mildly halotolerant, endospore-forming bacterium, FJAT-13985T, was isolated from the internal tissues of Mesona chinensis root. Strain FJAT-13985T grew at 20–45 °C (optimum 30 °C) and pH 5.7–9.0 (optimum pH 7.0) and in the presence of 0–2 % (w/v) NaCl [optimum 1 % (w/v)]. The strain was catalase-positive and oxidase-negative. The cell wall of strain FJAT-13985T contained meso-diaminopimelic acid and the predominant isoprenoid quinone was MK-7 (97.4 %). The major fatty acids of the strain were anteiso-C15 : 0 (23.3 %) and iso-C15 : 0 (40.8 %). The DNA G+C content was 41.64 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain FJAT-13985T is a member of the genus
Bacillus
and is most closely related to
Bacillus drentensis
DSM 15600T (98.4 %),
Bacillus vireti
DSM 15602T (98.2 %) and
Bacillus novalis
DSM 15603T (98.3 %). DNA–DNA hybridization indicated that relatedness between strain FJAT-13985T and its closest relative,
B. drentensis
DSM 15600T, was 36.63 %. The phenotypic, chemotaxonomic and genotypic properties clearly indicate that strain FJAT-13985T represents a novel species of the genus
Bacillus
, for which the name
Bacillus
mesonae sp. nov. is proposed. The type strain is FJAT-13985T ( = DSM 25968T = CGMCC1.12238T).

Abstract
ABSTRACT
The family
Bacillaceae
constitutes a phenotypically diverse and globally ubiquitous assemblage of bacteria. Investigation into how evolution has shaped, and continues to shape, this family has relied on several widely ranging approaches from classical taxonomy, ecological field studies, and evolution in soil microcosms to genomic-scale phylogenetics, laboratory, and directed evolution experiments. One unifying characteristic of the
Bacillaceae
, the endospore, poses unique challenges to answering questions regarding both the calculation of evolutionary rates and claims of extreme longevity in ancient environmental samples.

Abstract
The Buda Thermal Karst System is an active hypogenic karst area that offers possibility for the analysis of biogenic cave formation. The aim of the present study was to gain information about morphological structure and genetic diversity of bacterial communities inhabiting the Diana-Hygieia Thermal Spring (DHTS). Using scanning electron microscopy, metal accumulating and unusual reticulated filaments were detected in large numbers in the DHTS biofilm samples. The phyla Actinobacteria, Firmicutes and Proteobacteria were represented by both bacterial strains and molecular clones but phyla Acidobacteria, Chlorobi, Chlorofexi, Gemmatimonadetes, Nitrospirae and Thermotogae only by molecular clones which showed the highest similarity to uncultured clone sequences originating from different environmental sources. The biofilm bacterial community proved to be somewhat more diverse than that of the water sample and the distribution of the dominant bacterial clones was different between biofilm and water samples. The majority of biofilm clones was affiliated with Deltaproteobacteria and Nitrospirae while the largest group of water clones was related to Betaproteobacteria. Considering the metabolic properties of known species related to the strains and molecular clones from DHTS, it can be assumed that these bacterial communities may participate in the local sulphur and iron cycles, and contribute to biogenic cave formation.

Abstract
A Gram-staining-positive, endospore-forming, moderately alkaliphilic bacterium, strain NPK15(T), was isolated from a typical sandy loam soil under long-term NPK fertilization in northern China and was subjected to a polyphasic taxonomic study. The diamino acid of the cell-wall peptidoglycan of strain NPK15(T) was found to be meso-diaminopimelic acid and the cell-wall sugars were xylose, glucose and traces of mannose. The only respiratory quinone found in strain NPK15(T) was menaquinone 7 (MK-7). The major cellular fatty acids were iso-C(15 : 0), anteiso-C(15 : 0), C(16 : 0) and C(16 : 1)ω6c/C(16 : 1)ω7c. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis of the strain based on its 16S rRNA gene sequence showed that it was related most closely to 'Bacillus thaonhiensis' KACC 17216 (99.59%), B. songklensis KCTC 13881(T) (99.52%) and B. abyssalis CCTCC AB 2012074(T) (99.00%). DNA-DNA hybridization results indicated that the strain was distinct from other species of the genus Bacillus, the degree of relatedness being 35.4% with B. abyssalis CCTCC AB 2012074(T), 39.7% with B. songklensis KCTC 13881(T) and 51.2% with 'B. thaonhiensis' KACC 17216. The DNA G+C content of strain NPK15(T) was 45.5 mol%. Phenotypic, chemotaxonomic and molecular analyses identified strain NPK15(T) as a member of a novel species of the genus Bacillus, for which the name Bacillus fengqiuensis sp. nov. is proposed. The type strain is NPK15(T) ( = DSM 26745(T) = CCTCC AB 2013156(T)).

Abstract
A rod shaped, non-motile, endospore forming, Gram-stain positive and moderately halotolerant strain, designated as NCCP-168(T), was isolated from salt mines sampled in the Karak district of Khyber Pakhtunkhwa Province in Pakistan. To delineate its taxonomic position, the strain was subjected to polyphasic characterization. Cells of strain NCCP-168(T) can grow at 10-40 (○)C (optimum at 30-35 (○)C), in a pH range of 5.0-9.0 (optimum at pH 8.0) and in 0-17 % (w/v) NaCl on agar medium. The phylogenetic analysis based on the 16S rRNA gene sequence showed that strain NCCP-168(T) belongs to the genus Bacillus with the highest similarity to Bacillus seohaeanensis BH724(T) (97.1 %), and less than 97 % similarity with other closely related taxa (95.6 % with B. subtilis subsp. subtilis NCIB3610(T)). DNA-DNA relatedness between strain NCCP-168(T) and the type strains of closely related species was lower than 30 %. Chemotaxonomic data (major menaquinone, MK-7; cell wall peptidoglycan type, A1γ [meso-diaminopimelic acid]; major fatty acids, iso-C15:0 29.9 %, anteiso-C15:0 29.3 %, iso-C16:0 11.4 %, iso-C14:0 8.9 % and anteiso-C17:0 7.0 %; major polar lipids, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine) support the affiliation of strain NCCP-168(T) with genus Bacillus. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain NCCP-168(T) can be distinguished from the closely related taxa and thus represents a novel species in the genus Bacillus, for which the name Bacillus pakistanensis sp. nov. is proposed, with the type strain NCCP-168(T) (= KCTC 13786(T) = DSM 24834(T) = JCM 18975(T)).

Abstract
Two bacterial strains (JC167T and JC168) were isolated from a soil sample collected from Mandpam, Tamilnadu, India. Colonies of both strains were orange and cells Gram-stain-positive. Cells were small rods, and formed terminal endospores of ellipsoidal to oval shape. Both strains were positive for catalase, oxidase and hydrolysis of starch/gelatin, and negative for chitin hydrolysis, H2S production, indole production and nitrate reduction activity. Major fatty acids of both strains (>5%) were anteiso-C15:0, iso-C16:0, iso-C15:0, anteiso-C17:0, iso-C14:0 and C16:0 with minor (<5 but >1%) amounts of iso-C17:0, anteiso-C17:0 B/iso-C17:0 I and C16:1ω11c. Diphosphatydilglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids of both strains. Cell wall amino acids were L-alanine, D-alanine, D-glutamic acid and meso-diaminopimelic acid. β-Carotene and five unidentified carotenoids were present in both strains. Mean genomic DNA G+C content was 53.4±1 mol% and the two strains were closely related (mean DNA-DNA hybridization>90%). 16S rRNA gene sequence comparisons of both strains indicated that they represent species of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes. Both strains had a sequence similarity of 97.6% with Bacillus saliphilus 6AGT and <96.8% with other members of the genus Bacillus. Sequence similarity between strain JC167T and 168 was 100%. Strain JC167T showed 25.8±1% reassociation (based on DNA-DNA hybridization) with B. saliphilus DSM 15402T (=6AGT). Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strain JC167T as a representative of a novel species of the genus Bacillus, for which the name Bacillus luteus sp. nov. is proposed. The type strain is JC167T (=KCTC 33100T=LMG 27257T).

Abstract
A strictly aerobic, Gram-stain positive, slightly halophilic strain, designated SCSIO 04524(T), was isolated from a deep sea sediment sample collected from the northern South China Sea at a depth of 3415 m. The isolate slightly embedded into the medium after 72 h incubation at 30 °C. Growth was found to occur on media with 0-10 % NaCl but extremely weak growth occurred without supplying NaCl. The predominant menaquinone was determined to be MK-7. The major cellular fatty acid identified was iso-C15:0. The diagnostic polar lipids were determined to be diphosphatidylglycerol, phosphatidyl methylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content was determined to be 38 mol%. 16S rRNA gene sequences analysis showed that this strain had the highest similarities with Bacillus carboniphilus JCM 9731(T) (94.7 %) and Bacillus endophyticus 2DT(T) (94.3 %). Phylogenetic analysis revealed that strain SCSIO 04524(T) formed a distinct lineage with Bacillus chungangensis CAU 348(T) and B. carboniphilus JCM 9731(T). Physiological characteristics including utilization of sole nitrogen and carbon sources, and chemotaxonomic properties of cellular fatty acids and polar lipids could readily distinguish strain SCSIO 04524(T) from its most closely related species. Based on this polyphasic taxonomic data, a new species, Bacillus oceani sp. nov., is proposed, with the type strain SCSIO 04524(T) (=DSM 26213(T) = KCTC 33077(T)).

Abstract
A novel thermotolerant bacterium, designated SgZ-8(T), was isolated from a compost sample. Cells were non-motile, endospore-forming, Gram-staining positive, oxidase-negative and catalase-positive. The isolate was able to grow at 20-65 °C (optimum 50 °C) and pH 6.0-9.0 (optimum 6.5-7.0), and tolerate up to 9.0 % NaCl (w/v) under aerobic conditions. Anaerobic growth occurred with anthraquinone-2,6-disulphonate (AQDS), fumarate and NO3(-) as electron acceptors. Phylogenetic analysis based on the16S rRNA and gyrB genes grouped strain SgZ-8(T) into the genus Bacillus, with the highest similarity to Bacillus badius JCM 12228(T) (96.2 % for 16S rRNA gene sequence and 83.5 % for gyrB gene sequence) among all recognized species in the genus Bacillus. The G+C content of the genomic DNA was 49.3 mol%. The major isoprenoid quinone was menaquinone 7 (MK-7) and the polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The major cellular fatty acid was iso-C16 : 0. On the basis of its phenotypic and phylogenetic properties, chemotaxonomic analysis and the results of physiological and biochemical tests, strain SgZ-8(T) ( = CCTCC AB 2012108(T) = KACC 16706(T)) was designated the type strain of a novel species of the genus Bacillus, for which the name Bacillus thermotolerans sp. nov. is proposed.

Abstract
Two novel thermophilic bacteria, designated SgZ-9(T) and SgZ-10(T), were isolated from compost. Cells of the two strains were catalase-positive, endospore-forming and Gram-staining-positive rods. Strain SgZ-9(T) was oxidase-positive and non-motile, and strain SgZ-10(T) was oxidase-negative and motile. The highest 16S rRNA gene sequence similarity for both strains SgZ-9(T) and SgZ-10(T) was observed with Bacillus fortis (97.5 % and 96.9 %, respectively). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SgZ-9(T) formed a cluster with B. fortis R-6514(T) and Bacillus fordii R-7190(T), and SgZ-10(T) formed a cluster with Bacillus farraginis R-6540(T). The DNA-DNA pairing studies showed that SgZ-9(T) displayed 41.6 % and 30.7 % relatedness to the type strains of B. fortis and B. fordii, respectively. The 16S rRNA gene sequence similarity between strains SgZ-9(T) and SgZ-10(T) was 97.2 %, and the level of DNA-DNA relatedness between them was 39.2 %. The DNA G+C content of SgZ-9(T) and SgZ-10(T) was 45.3 and 47.9 mol%, respectively. Chemotaxonomic analysis revealed that both strains contained the menaquinone 7 (MK-7) as the predominant respiratory quinone. The major cellular fatty acids (>5 %) were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C17 : 0 in SgZ-9(T) and iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0, anteiso-C17 : 0 and iso-C16 : 0 in SgZ-10(T). Based on the phenotypic characteristics, chemotaxonomic features, DNA-DNA hybridization with the nearest phylogenetic neighbours and phylogenetic analysis based on the 16S rRNA gene sequences, the two strains were determined to be two distinct novel species in the genus Bacillus, and the names proposed are Bacillus composti sp. nov. SgZ-9(T) ( = CCTCC AB2012109(T) = KACC 16872(T)) and Bacillus thermophilus sp. nov. SgZ-10(T) (CCTCC AB2012110(T) = KACC 16873(T)).

Abstract
A Gram-reaction-positive, facultatively anaerobic, motile, endospore-forming, rod-shaped strain, designated SgZ-7(T), was isolated from a windrow compost pile and was characterized by means of a polyphasic approach. Growth occurred with 0-3 % (w/v) NaCl (optimum 1 %), at pH 6.0-10.0 (optimum pH 7.2) and at 40-60 °C (optimum 50 °C). The main respiratory quinone was MK-7. The predominant polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The DNA G+C content was 46.6 mol%. The phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain SgZ-7(T) should be assigned to the genus Bacillus and was related most closely to Bacillus drentensis LMG 21831(T) (sequence similarity 97.2 %). The result of the DNA-DNA hybridization experiment revealed a low relatedness (27.2 %) between the isolate and B. drentensis LMG 21831(T). The results of phenotypic, chemotaxonomic and genotypic analyses clearly indicated that strain SgZ-7(T) represents a novel species, for which the name Bacillus thermocopriae sp. nov. is proposed. The type strain is SgZ-7(T) (= CCTCC AB 2012030(T) = KACC 16700(T)).

Abstract
A novel Gram-staining-positive, rod-shaped, motile, strictly aerobic, endospore-forming bacterium, designated WCC 4585(T), was isolated from a pharmaceutical production line. The organism grew optimally at 30 °C, at pH 8 and in the presence of 0.5 % (w/v) NaCl. Oval endospores were formed subterminally and terminally in swollen sporangia. The cell-wall diamino acid was meso-diaminopimelic acid (type A1γ) and the genomic DNA G+C content was 38.7 mol%. The major menaquinone was MK-7. The cellular fatty acid profile contained major amounts of iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0, and the cellular phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The isolate was most closely related to Bacillus oceanisediminis H2(T), Bacillus infantis SMC 4352-1(T), Bacillus firmus NCIMB 9366(T), Bacillus circulans ATCC 4513(T) and Bacillus horneckiae DSM 23495(T) with which it shared less than 98.0 % 16S rRNA gene sequence similarity. DNA-DNA relatedness values between strain WCC 4585(T) and five type strains of related species were ≤27 % and sequence similarity values based on groEL sequences were ≤88.7 %. On the basis of the characteristics presented, strain WCC 4585(T) is proposed to represent a novel species, Bacillus gottheilii sp. nov. The type strain is WCC 4585(T)( = DSM 23668(T) = CCUG 59876(T) = LMG 25856(T)).

Abstract
A Gram-positive, aerobic, non-motile, endospore-forming rod, designated DS22T, was isolated from a drinking-water treatment plant. Cells were catalase- and oxidase-positive. Growth occurred at 15–37 °C, at pH 7–10 and with <8 % (w/v) NaCl (optimum growth: 30 °C, pH 7–8 and 1–3 % NaCl). The major respiratory quinone was menaquinone 7, the G+C content of the genomic DNA was 36.5 mol% and the cell wall contained meso-diaminopimelic acid. On the basis of 16S rRNA gene sequence analysis, strain DS22T was a member of the genus Bacillus. Its closest phylogenetic neighbours were Bacillus horneckiae NRRL B-59162T (98.5 % 16S rRNA gene sequence similarity), Bacillus oceanisediminis H2T (97.9 %), Bacillus infantis SMC 4352-1T (97.4 %), Bacillus firmus IAM 12464T (96.8 %) and Bacillus muralis LMG 20238T (96.8 %). DNA–DNA hybridization, and biochemical and physiological characterization allowed the differentiation of strain DS22T from its closest phylogenetic neighbours. The data supports the proposal of a novel species, Bacillus purgationiresistans sp. nov.; the type strain is DS22T ( = DSM 23494T = NRRL B-59432T = LMG 25783T).
