Abstract
A Gram-stain-positive aerobic, rod-shaped, spore-producing bacterium forming colonies with convex elevation and a smooth, intact margin was isolated from a freshwater sample collected from a well situated in an agricultural field. The 16S rRNA gene sequence of the isolated strain BA0131T showed the highest sequence similarity to Lysinibacillus yapensis ylb-03T (99.25%) followed by Ureibacillus chungkukjangi 2RL3-2T (98.91%) and U. sinduriensis BLB-1T (98.65%). The strain BA0131T was oxidase and catalase positive and urease negative. It also tested positive for esculin hydrolysis and reduction of potassium nitrate, unlike its phylogenetically closest relatives. The predominant fatty acids in strain BA0131T included were anteiso-C15:0, iso-C16:0, iso-C15:0, iso-C14:0 and the major polar lipids comprised were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. The respiratory quinones identified in strain BA0131T were MK8 (H2) (major) and MK8 (minor). The strain BA0131T shared the lowest dDDH values with L. yapensis ylb-03T (21%) followed by U. chungkukjangi 2RL3-2T (24.2%) and U. sinduriensis BLB-1T (26.4%) suggesting a closer genetic relationship U. sinduriensis BLB-1T. The ANI percentage supported the close relatedness with U. sinduriensis BLB-1T (83.61%) followed by U. chungkukjangi 2RL3-2T (82.03%) and U. yapensis ylb-03T (79.57%). The core genome-based phylogeny constructed using over 13,704 amino acid positions and 92 core genes revealed the distinct phylogenetic position of strain BA0131T among the genus Ureibacillus. The distinct physiological, biochemical characteristics and genotypic relatedness data indicate the strain BA0131T represents a novel species of the genus Ureibacillus for which the name Ureibacillus aquaedulcis sp. nov. (Type strain, BA0131T = MCC 5284 = JCM 36475) is proposed. Additionally, based on extensive genomic and phylogenetic analyses, we propose reclassification of two species, L. yapensis and L. antri, as U. yapensis comb. nov. (Type strain, ylb-03T = JCM 32871T = MCCC 1A12698T) and U. antri (Type strain, SYSU K30002T = CGMCC 1.13504T = KCTC 33955T).

Abstract
Microbes are ubiquitous in the biosphere, and their therapeutic and ecological potential is not much more explored and still needs to be explored more. The bacilli are a heterogeneous group of Gram-negative and Gram-positive bacteria. Lysinibacillus are dominantly found as motile, spore-forming, Gram-positive bacilli belonging to phylum Firmicutes and the family Bacillaceae. Lysinibacillus species initially came into light due to their insecticidal and larvicidal properties. Bacillus thuringiensis, a well-known insecticidal Lysinibacillus, can control many insect vectors, including a malarial vector and another, a Plasmodium vector that transmits infectious microbes in humans. Now its potential in the environment as a piece of green machinery for remediation of heavy metal is used. Moreover, some species of Lysinibacillus have antimicrobial potential due to the bacteriocin, peptide antibiotics, and other therapeutic molecules. Thus, this review will explore the biological disease control abilities, food preservative, therapeutic, plant growth-promoting, bioremediation, and entomopathogenic potentials of the genus Lysinibacillus.

Gupta RS, Patel S. Robust Demarcation of the Family Caryophanaceae ( Planococcaceae) and Its Different Genera Including Three Novel Genera Based on Phylogenomics and Highly Specific Molecular Signatures. Front Microbiol 2020; 10:2821. [PMID: 32010063 PMCID: PMC6971209 DOI: 10.3389/fmicb.2019.02821] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 11/20/2019] [Indexed: 12/12/2022] Open
Abstract
The family Caryophanaceae/Planococcaceae is a taxonomically heterogeneous assemblage of >100 species classified within 13 genera, many of which are polyphyletic. Exhibiting considerable phylogenetic overlap with other families, primarily Bacillaceae, the evolutionary history of this family, containing the potent mosquitocidal species Lysinibacillus sphaericus, remains incoherent. To develop a reliable phylogenetic and taxonomic framework for the family Caryophanaceae/Planococcaceae and its genera, we report comprehensive phylogenetic and comparative genomic analyses on 124 genome sequences from all available Caryophanaceae/Planococcaceae and representative Bacillaceae species. Phylogenetic trees were constructed based on multiple datasets of proteins including 819 core proteins for this group and 87 conserved Firmicutes proteins. Using the core proteins, pairwise average amino acid identity was also determined. In parallel, comparative analyses on protein sequences from these species have identified 92 unique molecular markers (synapomorphies) consisting of conserved signature indels that are specifically shared by either the entire family Caryophanaceae/Planococcaceae or different monophyletic clades present within this family, enabling their reliable demarcation in molecular terms. Based on multiple lines of investigations, 18 monophyletic clades can be reliably distinguished within the family Caryophanaceae/Planococcaceae based on their phylogenetic affinities and identified molecular signatures. Some of these clades are comprised of species from several polyphyletic genera within this family as well as other families. Based on our results, we are proposing the creation of three novel genera within the family Caryophanaceae/Planococcaceae, namely Metalysinibacillus gen. nov., Metasolibacillus gen. nov., and Metaplanococcus gen. nov., as well as the transfer of 25 misclassified species from the families Caryophanaceae/Planococcaceae and Bacillaceae into these three genera and in Planococcus, Solibacillus, Sporosarcina, and Ureibacillus genera. These amendments establish a coherent taxonomy and evolutionary history for the family Caryophanaceae/Planococcaceae, and the described molecular markers provide novel means for diagnostic, genetic, and biochemical studies. Lastly, we are also proposing a consolidation of the family Planococcaceae within the emended family Caryophanaceae.

Abstract
Lysinibacillus massiliensis, formerly Bacillus massiliensis, is an environmental Gram-positive bacillus that is generally non-pathogenic. Rare case reports in immunosuppressed patients have described sepsis with this organism. In this study, we report a case of L massiliensis as a cause of infectious panniculitis mimicking erythema nodosum after infusion of autologous adipose-derived stem cells in an immunosuppressed patient with refractory Crohn’s disease. This case highlights the importance of care providers to consider exposures and host factors when interpreting culture results with otherwise benign organisms.

Abstract
A Gram-positive, aerobic, motile, rod-shaped bacterium, designated strain C9(T), was isolated from surface sterilised corn roots (Zea mays cv. Xinken-5) and found to be able to produce indole-3-acetic acid. A polyphasic taxonomic study was carried out to determine the status of strain C9(T). The major cellular fatty acids were found to contain iso-C15:0, anteiso-C15:0 and anteiso-C17:0, and the only menaquinone was identified as MK-7. The polar lipid profile was found to contain diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids and an unidentified lipid. The cell wall peptidoglycan was found to be of the A4α L-Lys-D-Asp type and the whole cell sugar was found to be glucose. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain C9(T) belongs to the genus Lysinibacillus and is closely related to Lysinibacillus chungkukjangi NBRC 108948(T) (98.1 % similarity) and Lysinibacillus sinduriensis DSM 27595(T) (98.0 %). However, the low levels of DNA-DNA relatedness and some differential phenotypic characteristics allowed the strain to be distinguished from its close relatives. Therefore, it is concluded that strain C9(T) represents a novel species of the genus Lysinibacillus, for which the name Lysinibacillus endophyticus sp. nov. is proposed. The type strain is C9(T) (=DSM 100506(T) = CGMCC 1.15291(T)).

Abstract
A Gram-stain-positive, rod-shaped, facultatively anaerobic, endospore-forming bacterium (designated strain SC03T) was isolated from the aerobic treatment sludge of a coking plant (Shaoguan City, China). The optimal pH and temperature for growth were pH 7.0 and 35 °C. On the basis of 16S rRNA gene sequence analysis, strain SC03T was related to the genus Lysinibacillus and the similarity between strain SC03T and the most closely related type strain, Lysinibacillus macroides LMG 18474T, was 94.4 %. The genomic G+C content of the DNA of strain SC03T was 41.2 mol%. Chemotaxonomic data supported the affiliation of strain SC03T to the genus Lysinibacillus. These properties include MK-7 as the predominant menaquinone; iso-C15 : 0 and iso-C16 : 0 as major fatty acids; A4α (l-Lys-d-Asp) as the cell-wall peptidoglycan type; and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine plus three unknown phospholipids as polar lipids. The phenotypic, phylogenetic and chemotaxonomic characters enable the differentiation of strain SC03T from recognized Lysinibacillus species. Thus, strain SC03T represents a novel species of the genus Lysinibacillus, for which the name Lysinibacillus cresolivorans sp. nov. is proposed. The type strain is SC03T ( = NRRL B-59352T = CCTCC M 208210T).

Abstract
Investigation of the microbial diversity of Ntoba Mbodi, an African food made from the alkaline fermentation of cassava leaves, revealed the presence of a Gram-positive, catalase-positive, aerobic, motile and rod-shaped endospore-forming bacterium (NM73) with unusual phenotypic and genotypic characteristics. The analysis of the 16S rRNA gene sequence revealed that the isolate was most closely related to Lysinibacillus meyeri WS 4626T (98.93%), Lysinibacillus xylanilyticus XDB9T (96.95%) and Lysinibacillus odysseyi 34hs-1T (96.94%). The DNA-DNA relatedness of the isolate with L. meyeri LMG 26643T, L. xylanilyticus DSM 23493T and L. odysseyi DSM 18869T was 41%, 16% and 15%, respectively. The internal transcribed spacer-PCR profile of the isolate was different from those of closely related bacteria. The cell-wall peptidoglycan type was A4α, L-Lys-D-Asp and the major fatty acids were iso-C15:0, anteiso-C15:0, anteiso-C17:0 and iso-C17:0 and iso-C17:1ω10c. The polar lipids included phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphoaminolipid, aminolipid, two phospholipids and two unknown lipids. The predominant menaquinones were MK-7 and MK-6. Ribose was the only whole-cell sugar detected. The DNA G+C content was 38 mol%. Based on the results of the phenotypic and genotypic characterization, it was concluded that the isolate represents a novel species of the genus Lysinibacillus, for which the name of Lysinibacillus louembei sp. nov. is proposed. NM73T ( = DSM 25583T = LMG 26837T) represents the type strain.

Characteristics and phylogeny of Bacillus cereus strains isolated from Maari, a traditional West African food condiment. Int J Food Microbiol 2014; 196:70-8. [PMID: 25528535 DOI: 10.1016/j.ijfoodmicro.2014.11.026] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2014] [Revised: 11/10/2014] [Accepted: 11/24/2014] [Indexed: 10/24/2022]
Abstract
Maari is a spontaneously fermented food condiment made from baobab tree seeds in West African countries. This type of product is considered to be safe, being consumed by millions of people on a daily basis. However, due to the spontaneous nature of the fermentation the human pathogen Bacillus cereus occasionally occurs in Maari. This study characterizes succession patterns and pathogenic potential of B. cereus isolated from the raw materials (ash, water from a drilled well (DW) and potash), seed mash throughout fermentation (0-96h), after steam cooking and sun drying (final product) from two production sites of Maari. Aerobic mesophilic bacterial (AMB) counts in raw materials were of 10(5)cfu/ml in DW, and ranged between 6.5×10(3) and 1.2×10(4)cfu/g in potash, 10(9)-10(10)cfu/g in seed mash during fermentation and 10(7) - 10(9) after sun drying. Fifty three out of total 290 AMB isolates were identified as B. cereus sensu lato by use of ITS-PCR and grouped into 3 groups using PCR fingerprinting based on Escherichia coli phage-M13 primer (M13-PCR). As determined by panC gene sequencing, the isolates of B. cereus belonged to PanC types III and IV with potential for high cytotoxicity. Phylogenetic analysis of concatenated sequences of glpF, gmk, ilvD, pta, pur, pycA and tpi revealed that the M13-PCR group 1 isolates were related to B. cereus biovar anthracis CI, while the M13-PCR group 2 isolates were identical to cereulide (emetic toxin) producing B. cereus strains. The M13-PCR group 1 isolates harboured poly-γ-D-glutamic acid capsule biosynthesis genes capA, capB and capC showing 99-100% identity with the environmental B. cereus isolate 03BB108. Presence of cesB of the cereulide synthetase gene cluster was confirmed by PCR in M13-PCR group 2 isolates. The B. cereus harbouring the cap genes were found in potash, DW, cooking water and at 8h fermentation. The "emetic" type B. cereus were present in DW, the seed mash at 48-72h of fermentation and in the final product, while the remaining isolates (PanC type IV) were detected in ash, at 48-72h fermentation and in the final product. This work sheds light on the succession and pathogenic potential of B. cereus species in traditional West African food condiment and clarifies their phylogenetic relatedness to B. cereus biovar anthracis. Future implementation of GMP and HACCP and development of starter cultures for controlled Maari fermentations will help to ensure a safe product.

Abstract
A novel Gram-positive, fluoroglycofen-degrading bacterium, designated cmg86(T), was isolated from herbicide contaminated soil collected from Tongjing, Jiangsu province, China. Strain cmg86(T) was found to be aerobic, motile, endospore-forming rods. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain cmg86(T) belongs to the genus Lysinibacillus and showed the highest sequence similarity to Lysinibacillus meyeri DSM 25057(T) (97.9 %) and Lysinibacillus odysseyi KCTC 3961(T) (96.6 %). The cell-wall peptidoglycan type was determined to be A4α (L-Lys-D-Asp), which is consistent with the cell-wall characteristics of the genus Lysinibacillus. The predominant respiratory quinones were identified as menaquinone-7 (MK-7, 89.5 %) and meanaquinone-6 (MK-6, 8.9 %), and the major fatty acids were identified as iso-C15:0, anteiso-C15:0 and antesio-C17:0. The major polar lipids were found to be phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. The genomic DNA G+C content of strain cmg86(T) was determined to be 37.6 mol%. The results of this study support the conclusion that strain cmg86(T) represents a novel species of the genus Lysinibacillus for which the name and Lysinibacillus fluoroglycofenilyticus sp. nov. is proposed. The type strain is cmg86(T) (=KCTC 33183(T) = CCTCC AB 2013247(T)).

Abstract
A novel aerobic, halotolerant bacterium, designated strain LAM612(T), was isolated from saline-alkaline soil samples from Lingxian County, Shandong Province, China. Cells of strain LAM612(T) were Gram-reaction-positive, endospore-forming, motile and rod-shaped. The optimal temperature and pH for growth were 35 °C and pH 6.0, respectively. Strain LAM612(T) could grow in the presence of up to 10% (w/v) NaCl. The genomic DNA G+C conten was 36.4 mol% as detected by the T(m) method. Comparative analysis of 16S rRNA gene sequences revealed that LAM612(T) was closely related to Lysinibacillus sinduriensis KACC 16611(T) (98.0%), L. chungkukjangi KACC 16626(T) (97.5%), L. massiliensis KCTC 13178(T) (97.4%), L. xylanilyticus KACC 15113(T) (97.2%), L. macroides DSM 54(T) (97.0%) and L. manganicus DSM 26584(T) (96.5%). The DNA-DNA hybridization values between strain LAM612(T) and its closest relatives ranged from 20.6% to 41.9%. The major fatty acids of strain LAM612(T) were iso-C(15 : 0) (40.8%), iso-C(16 : 0) (15.2%) and anteiso-C(15 : 0) (10.8%). The cell-wall peptidoglycan content was A4α (L-Lys-D-Asp). The predominant menaquinone was MK-7 and the main polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unknown phospholipids, five unknown glycolipids and an unknown lipid. Based on the DNA-DNA hybridization results and phenotypic, phylogenetic and chemotaxonomic properties, strain LAM612(T) could be distinguished from the recognized species of the genus Lysinibacillus, and was suggested to represent a novel species of this genus, for which the name Lysinibacillus halotolerans sp. nov. is proposed. The type strain is LAM612(T) ( = ACCC 00718(T) = JCM 19611(T)).

Abstract
A Gram-stain-positive, aerobic, motile, rod-shaped bacterium, designated strain Mn1-7T, was isolated from manganese mining soil in Tianjin, China. The closest phylogenetic relatives were
Lysinibacillus massiliensis
CCUG 49529T (97.2 % 16S rRNA gene sequence similarity),
L. xylanilyticus
XDB9T (96.7 %),
L. sinduriensis
JCM 15800T (96.2 %),
L. odysseyi
NBRC 100172T (95.9 %) and
L. boronitolerans
NBRC 103108T (95.4 %) (the type species of the genus). DNA–DNA hybridization values for strain Mn1-7T with the type strains of
L. massiliensis
and
L. sinduriensis
were 24.9 and 27.7 %, respectively. The genomic DNA G+C content was 38.4 mol%. The major menaquinone was MK-7 and the major fatty acids were iso-C15 : 0, iso-C16 : 0 and iso-C14 : 0. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The cell-wall peptidoglycan was type A4α (l-Lys–d-Asp), and the predominant cell-wall sugar was xylose. DNA–DNA hybridization results and comparison of phenotypic and chemotaxonomic characters between strain Mn1-7T and the phylogenetically most closely related strains revealed that the isolate represents a novel species of the genus
Lysinibacillus
, for which the name
Lysinibacillus
manganicus sp. nov. is proposed. The type strain is Mn1-7T ( = DSM 26584T = CCTCC AB 2012916T).

Abstract
A Gram-positive-staining, aerobic, endospore-forming bacterium, isolated as a contamination from an enrichment of enteric bacteria from surface water, was studied using a polyphasic taxonomic approach. 16S rRNA gene sequence similarity comparisons revealed that strain FSt3AT was grouped in the genus
Lysinibacillus
, most closely related to
Lysinibacillus xylanilyticus
XDB9T (98.1 %),
Lysinibacillus parviboronicapiens
BAM-582T and
Lysinibacillus sphaericus
DSM 28T (both 98.0 %). The 16S rRNA gene sequence similarity to other species of the genus
Lysinibacillus
was <97.5 %. The allocation to the genus
Lysinibacillus
was supported by a detailed chemotaxonomic characterization revealing a cell wall containing alanine, glutamic acid, aspartic acid and the diagnostic diamino acid lysine in a molar ratio of 1.6 : 1 : 0.9 : 0.8 (peptidoglycan type A4α), the major menaquinones MK-7 and MK-6, and polar lipids consisting of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unknown phospholipids, one unknown aminophospholipid and one unidentified aminolipid. The major fatty acids were iso- and anteiso-branched fatty acids. DNA–DNA hybridizations with the type strains of the most closely related species,
L. parviboronicapiens
DSM 25242T,
L. xylanilyticus
DSM 23493T and
L. sphaericus
DSM 28T, in addition to the results of physiological and biochemical tests, allowed genotypic and phenotypic differentiation of strain FSt3AT from these related species. Thus, FSt3AT represents a novel species of the genus
Lysinibacillus
, for which the name
Lysinibacillus
contaminans sp. nov. is proposed, with FSt3AT ( = CCM 8383T = DSM 25560T = CIP 110362T) as the type strain.
