Endosaccharibacter trunci gen. nov., sp. nov. and Rhizosaccharibacter radicis gen. nov., sp. nov., two novel bacteria of the family Acetobacteraceae isolated from sugarcane. Heliyon 2024; 10:e32825. [PMID: 39005926 PMCID: PMC11239595 DOI: 10.1016/j.heliyon.2024.e32825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 05/27/2024] [Accepted: 06/10/2024] [Indexed: 07/16/2024] Open
Abstract
Two novel endophytic bacterial strains, designated KSS8T and KSS12T, were isolated from the stems and roots of sugarcane, respectively, collected in Nakhon Ratchasima, Thailand. They were Gram-stain-negative, aerobic, and rod-shaped. The strain KSS8T was a motile bacterium with a subpolar flagellum, while the strain KSS12T was non-motile. Strains KSS8T and KSS12T were closely related to Lichenicola cladoniae PAMC 26569T (97.3 and 95.6 %, respectively) and Lichenicoccus roseus KEBCLARHB70RT (97.2 and 95.8 %, respectively) based on the similarity on their 16S rRNA gene sequence. This similarity corresponded to their phylogenomic positions within the evolutionary radiation of the family Acetobacteraceae. The average nucleotide identities and digital DNA-DNA hybridization values between the genome sequences of the two strains and other genera were significantly lower than the defined threshold values of 95-96 % and 70 %, respectively, which are used for the delineation of prokaryotic species. Both strains contained summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C16:0, C19:0 cyclo ω8c, C18:0, and C18:1 2OH as the predominant cellular fatty acids, but C18:3 ω6c (6, 9, 12) were found only in strain KSS12T. Based on phenotypic, chemotaxonomic, phylogenetic, and genomic analyses, these strains clearly represented two novel genera within the family Acetobacteraceae, for which the name Endosaccharibacter gen. nov., with the type species Endosaccharibacter trunci sp. nov. (type strain, KSS8T = TBRC 14669T = NBRC 115232T = KCTC 92115T = LMG 32414T) and the name Rhizosacchari bacter gen. nov., with the type species Rhizosaccharibacter radicis sp. nov. (type strain, KSS12T = TBRC 13066T = NBRC 114898T = KCTC 82433T = LMG 32137T) are proposed.

Abstract
Acetic acid, a colourless liquid organic acid with a characteristic acrid smell, is obtained naturally and has applications in both the food and pharmaceutical industries. It has been reported to have beneficial uses for lifestyle-related diseases, and its efficient disinfectant properties are well known. In this study, an alginate crosslinked with Ca2+ hydrogel film was treated with acetic acid to explore its biological properties for biomedicine. The results showed that the novel calcium alginate/acetic acid film was biocompatible in vitro using human keratinocyte cells and in vivo with Caenorhabditis elegans. It also had antiviral properties against enveloped and non-enveloped viruses and anticancer properties against melanoma and colon cancer cells. This novel film thus showed promise for the biomedical and pharmaceutical industries, with applications for fabricating broad-spectrum antiviral and anticancer materials.

Abstract
Polyphasic taxonomic and comparative genomic analyses revealed that a series of lambic beer isolates including strain LMG 32668T and the kombucha isolate LMG 32879 represent a novel species among the acetic acid bacteria, with Acidomonas methanolica as the nearest phylogenomic neighbor with a valid name. Overall genomic relatedness indices and phylogenomic and physiological analyses revealed that this novel species was best classified in a novel genus for which we propose the name Brytella acorum gen. nov., sp. nov., with LMG 32668T (=CECT 30723T) as the type strain. The B. acorum genomes encode a complete but modified tricarboxylic acid cycle, and complete pentose phosphate, pyruvate oxidation and gluconeogenesis pathways. The absence of 6-phosphofructokinase which rendered the glycolysis pathway non-functional, and an energy metabolism that included both aerobic respiration and oxidative fermentation are typical metabolic characteristics of acetic acid bacteria. Neither genome encodes nitrogen fixation or nitrate reduction genes, but both genomes encode genes for the biosynthesis of a broad range of amino acids. Antibiotic resistance genes or virulence factors are absent.

Abstract
BACKGROUND Fermented rice flour (khao-khab, a non-glutinous rice) and related products are Thai traditional products. The types of acetic acid bacteria (AAB) microflora in khao-khab have not been reported. In this study, Acetobacter strains were isolated and identified based on the phenotypic and chemotaxonomic characteristics and molecular aspects. RESULTS Twenty-five acetic acid bacteria isolated from fermented rice products and a starter for sweetened rice in Thailand by an enrichment culture approach, were assigned to the genus Acetobacter by phenotypic and chemotaxonomic characterisations. On the basis of the 16S rRNA gene sequence and 16S-23S rRNA gene ITS restriction analyses, 25 isolates were divided into six groups and identified at the specific level: (1) Group 1 included five isolates, which were identified as A. indonesiensis; (2) Group 2 included two isolates, which were identified as A. lovaniensis; (3) Group 3 included one isolate, which was identified as A. orientalis; (4) Group 4 included eleven isolates, which were identified as A. pasteurianus; (5) Group 5 included three isolates, which were identified as A. syzygii and (6) Group 6 included three isolates, which were unidentified and considered to constitute a new species. CONCLUSION Results revealed that various Acetobacter species were distributed in Thai fermented rice flour and related products. A novel Acetobacter species was isolated from the product.

Abstract
A Gram-positive, rod-shaped, strictly aerobic, spore-forming, moderately halophilic bacterium, designated strain SSK2-2T, was isolated from fermented shrimp paste (ka-pi) produced in Thailand. It contained MK-7 as the predominant menaquinone and meso-diaminopimelic acid in the cell-wall peptidoglycan. The isolate grew at 8-43 degrees C, pH 6-9 and in 0.5-24% (w/v) NaCl (optimum, 6-14% NaCl). The major cellular fatty acids were anteiso-C15:0 and anteiso-C17:0. Phosphatidylglycerol and diphosphatidylglycerol were the major polar lipid components. The DNA G+C content was 39.7 mol%. Comparative 16S rRNA gene sequence analyses showed that strain SSK2-2T was most closely related to Oceanobacillus picturae KCTC 3821T with 98.7% sequence similarity. Based on phenotypic and molecular features combined with DNA-DNA hybridization results (<or=24.9% with O. picturae KCTC 3821T), this strain represents a novel species of the genus Oceanobacillus for which the name Oceanobacillus kapialis sp. nov. is proposed; the type strain is SSK2-2T (=KCTC 13177T=PCU 300T=TISTR 1858T).

Abstract
Fifteen strains of moderately halophilic, Gram-positive cocci were isolated from a traditional fermented shrimp paste ('ka-pi') produced in Thailand. These bacteria were strictly aerobic, non-motile, non-sporulating and catalase- and oxidase-positive. They produced orange pigment and grew in the presence of 1.5-25 % (w/v) NaCl. They grew optimally in 10 % (w/v) NaCl, at pH 8.5 and at 37 degrees C. The cell-wall peptidoglycan was of l-Lys type. Menaquinone with six isoprene units (MK-6) was a major component. The dominant cellular fatty acids were anteiso-C(15 : 0) and iso-C(15 : 0). DNA G+C contents were in the range 44.5-47.5 mol%. Comparative 16S rRNA gene sequence analyses indicated that representative strain PN1-2(T) was related most closely to Salinicoccus roseus JCM 14630(T), with 97.3 % similarity. The other novel strains were included in the same species based on their levels of DNA-DNA relatedness to strain PN1-2(T) (> or =76.6 %) but showed low DNA-DNA relatedness to S. roseus JCM 14630(T) (21.7 %). On the basis of the phenotypic and molecular data presented, the 15 novel strains are suggested to represent a single novel species of the genus Salinicoccus, for which the name Salinicoccus siamensis sp. nov. is proposed. The type strain is PN1-2(T) (=JCM 12822(T) =PCU 242(T) =TISTR 1562(T)).

Abstract
Chronic granulomatous disease (CGD) is an inherited immune deficiency characterized by increased susceptibility to infection with Staphylococcus, certain gram-negative bacteria, and fungi. Granulibacter bethesdensis, a newly described genus and species within the family Acetobacteraceae, was recently isolated from four CGD patients residing in geographically distinct locales who presented with fever and lymphadenitis. We sequenced the genome of the reference strain of Granulibacter bethesdensis, which was isolated from lymph nodes of the original patient. The genome contains 2,708,355 base pairs in a single circular chromosome, in which 2,437 putative open reading frames (ORFs) were identified, 1,470 of which share sequence similarity with ORFs in the nonpathogenic but related Gluconobacter oxydans genome. Included in the 967 ORFs that are unique to G. bethesdensis are ORFs potentially important for virulence, adherence, DNA uptake, and methanol utilization. GC% values and best BLAST analysis suggested that some of these unique ORFs were recently acquired. Comparison of G. bethesdensis to other known CGD pathogens demonstrated conservation of some putative virulence factors, suggesting possible common mechanisms involved in pathogenesis in CGD. Genotyping of the four patient isolates by use of a custom microarray demonstrated genome-wide variations in regions encoding DNA uptake systems and transcriptional regulators and in hypothetical ORFs. G. bethesdensis is a genetically diverse emerging human pathogen that may have recently acquired virulence factors new to this family of organisms.

Abstract
A Gram-negative, aerobic, coccobacillus to rod-shaped bacterium was isolated from three patients with chronic granulomatous disease. The organism was subjected to a polyphasic taxonomic study. A multilocus phylogenetic analysis based on the 16S rRNA gene, the internal transcribed spacer (ITS) region and the RecA protein demonstrated that the organism belongs to a new sublineage within the acetic acid bacteria in the family Acetobacteraceae. Phenotypic features are summarized as follows: the organism grew at an optimum temperature of 35-37 degrees C and optimum pH of 5.0-6.5. It produced a yellow pigment, oxidized lactate and acetate, the latter weakly, produced little acetic acid from ethanol and could use methanol as a sole carbon source. The two major fatty acids were a straight-chain unsaturated acid (C18:1omega7c) and C16:0. The DNA base composition was 59.1 mol% G+C. The very weak production of acetic acid from ethanol, the ability to use methanol, the yellow pigmentation and high optimum temperature for growth distinguished this organism from other acetic acid bacteria. The unique phylogenetic and phenotypic characteristics suggest that the bacterium should be classified within a separate genus, for which the name Granulibacter bethesdensis gen. nov., sp. nov. is proposed. The type strain is CGDNIH1T (=ATCC BAA-1260T=DSM 17861T).

Abstract
Two strains of strictly aerobic, moderately halophilic Gram-positive rods were isolated from fermented shrimp paste (‘ka-pi’) produced in Thailand. They produced a red pigment and grew optimally in the presence of 5–30 % NaCl. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The major cellular fatty acid was anteiso-C15 : 0. Phosphatidylglycerol, diphosphatidylglycerol and two unidentified glycolipids were found to be the major polar lipid components. The DNA G+C content was 41.2–41.6 mol%. Comparative 16S rRNA gene sequence analyses showed that strain PN7-6T was most closely related to Lentibacillus salarius KCTC 3911T with 96.5 % sequence similarity. On the basis of phenotypic and molecular properties, the two isolates represent a novel species of the genus Lentibacillus, for which the name Lentibacillus kapialis sp. nov. is proposed. The type strain is PN7-6T (=JCM 12580T=PCU 259T=TISTR 1551T).

Abstract
Fifteen strains of extremely halophilic bacteria were isolated from fish sauce (nam-pla) collected in Thailand at various stages of the fish-fermentation process. The isolates were strictly aerobic, spore-forming, Gram-positive rods. They grew optimally in the presence of 20–26 % NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0. Polar lipid analysis revealed the presence of phosphatidylglycerol, diphosphatidylglycerol and two unidentified glycolipids. The DNA G+C content was 42.1–43.1 mol%. On the basis of the 16S rRNA gene sequence, a representative strain, PS11-2T, was found to be closely related to Lentibacillus juripiscarius JCM 12147T (97.3 % similarity). The 15 strains were included in the same species on the basis that the levels of DNA–DNA relatedness with strain PS11-2T were greater than 70 %. They could be distinguished from L. juripiscarius and other Lentibacillus species on the basis of several phenotypic characteristics and low levels of DNA–DNA relatedness (⩽19.4 %). Therefore, the strains represent a novel species of the genus Lentibacillus, for which the name Lentibacillus halophilus sp. nov. is proposed. The type strain is PS11-2T (=JCM 12149T=TISTR 1549T=PCU 240T).

Abstract
Chronic granulomatous disease (CGD) is a rare inherited disease of the phagocyte NADPH oxidase system causing defective production of toxic oxygen metabolites, impaired bacterial and fungal killing, and recurrent life-threatening infections. We identified a novel gram-negative rod in excised lymph nodes from a patient with CGD. Gram-negative rods grew on charcoal-yeast extract, but conventional tests could not identify it. The best 50 matches of the 16S rRNA (using BLAST) were all members of the family Acetobacteraceae, with the closest match being Gluconobacter sacchari. Patient serum showed specific band recognition in whole lysate immunoblot. We used mouse models of CGD to determine whether this organism was a genuine CGD pathogen. Intraperitoneal injection of gp91phox−/− (X-linked) and p47 phox −/− (autosomal recessive) mice with this bacterium led to larger burdens of organism recovered from knockout compared with wild-type mice. Knockout mouse lymph nodes had histopathology that was similar to that seen in our patient. We recovered organisms with 16S rRNA sequence identical to the patient's original isolate from the infected mice. We identified a novel gram-negative rod from a patient with CGD. To confirm its pathogenicity, we demonstrated specific immune reaction by high titer antibody, showed that it was able to cause similar disease when introduced into CGD, but not wild-type mice, and we recovered the same organism from pathologic lesions in these mice. Therefore, we have fulfilled Koch's postulates for a new pathogen. This is the first reported case of invasive human disease caused by any of the Acetobacteraceae. Polyphasic taxonomic analysis shows this organism to be a new genus and species for which we propose the name Granulobacter bethesdensis. As new bacteria continue to be discovered every year, it is inevitable that some of them will be found to cause human disease. The authors describe the isolation and characterization of a new bacterium, grown from a patient with chronic granulomatous disease (CGD). In this genetic disease, one of the main lines of defense against infection, the neutrophil, has a discrete defect in the generation of superoxide, leading to recurrent infections with a narrow spectrum of bacteria and fungi. This new organism was cultured from lymph nodes that had been inflamed for several months. To prove that this new bacterium was indeed a pathogen, Greenberg and colleagues measured specific antibody response in the patient: they inoculated CGD mice with this organism and reproduced the appearance of the human infection; they recovered the organism in pure growth from infected mouse spleens. This new bacterium belongs to the family Acetobacteraceae, bacteria that are found widely in the environment. They have a variety of industrial uses, such as the production of vinegar, but have never been reported to cause invasive human disease. Disease-causing organisms remain to be discovered. The researchers outline some of the steps that can be taken to verify the pathogenicity of novel organisms.

Abstract
Four strains of acetic acid bacteria were isolated from flowers collected in Thailand. In phylogenetic trees based on 16S rRNA gene sequences and 16S-23S rDNA internal transcribed spacer (ITS) region sequences, the four isolates were located in the lineage of the genus Gluconobacter and constituted a separate cluster from the known Gluconobacter species, Gluconobacter oxydans, Gluconobacter cerinus, and Gluconobacter frateurii. In addition, the isolates were distinguished from the known species by restriction analysis of 16S-23S rDNA ITS region PCR products using three restriction endonucleases Bsp1286I, MboII, and AvaII. The DNA base composition of the isolates ranged from 55.3-56.3 mol% G+C. The four isolates constituted a taxon separate from G. oxydans, G. cerinus, and G. frateurii on the basis of DNA-DNA similarities. Morphologically, physiologically, and biochemically, the four isolates were very similar to the type strains of G. oxydans, G. cerinus, and G. frateurii; however, the isolates were discriminated in their growth at 37 degrees C from the type strains of G. cerinus and G. frateurii, and in their growth on L-arabitol and meso-ribitol from the type strain of G. oxydans. The isolates showed no acid production from myo-inositol or melibiose, which differed from the type strains of the three known species. The major ubiquinone homologue was Q-10. On the basis of the results obtained, Gluconobacter thailandicus sp. nov. was proposed for the four isolates. The type strain is isolate F149-1(T) (=BCC 14116(T)=NBRC 100600(T)=JCM 12310(T)=TISTR 1533(T)=PCU 225(T)), which had 55.8 mol% G+C, isolated from a flower of the Indian cork tree (Millingtonia hortensis) collected in Bangkok, Thailand.
