Fatty Acids in Bacillus larvae, Bacillus lentimorbus, and Bacillus popilliae

The types of fatty acids produced by two strains each of Bacillus larvae, B. lentimorbus, and B. popilliae, and their distribution patterns, were studied by gas-liquid chromatography. All six organisms produced eight major fatty acids: six branched (iso-C(14), -C(15), -C(16), and -C(17), and anteiso-C(15) and -C(17)), two normal (n-C(14) and -C(16)), and two minor (n-C(15) and monounsaturated n-C(16)). In addition, some other trace acids were produced. Branched-chain fatty acids accounted for 54 to 85% of the total fatty acids. These compositions are similar to those previously found with 26 strains of 12 species of the genus Bacillus. Thus, an abundance of branched-chain fatty acids seems to be a characteristic of the biochemical nature of the genus Bacillus. It is noteworthy that marked differences between the nutritional requirements of the three insect pathogens used in the present study and those of the other 12 species of the genus Bacillus studied previously are not significantly reflected in their fatty acid composition.     

The fatty acids of calcareous sponges (Calcarea, Porifera)

Twenty-nine specimens of calcareous sponges (Class Calcarea, Phylum Porifera), covering thirteen representative species of the families Soleneiscidae, Leucaltidae, Levinellidae, Leucettidae, Clathrinidae, Sycettidae, Grantiidae, Jenkinidae, and Heteropiidae were analysed for their fatty acids. The fatty acids of Calcarea generally comprise saturated and monounsaturated linear (n-), and terminally methylated (iso-, anteiso-) C(14)-C(20) homologues. Furthermore, polyunsaturated C(22) fatty acids and the isoprenoic 4,8,12-trimethyltridecanoic acid were found. The most prominent compounds are n-C(16), iso-C(17), iso-C(18), n-C(18), n-C(20). In addition, a high abundance of the exotic 16-methyloctadecanoic acid (anteiso-C(19)) appears to be a characteristic trait of Calcarea. Long-chain 'demospongic acids', typically found in Demospongiae and Hexactinellida, are absent in Calcarea. The completely different strategy of calcarean fatty acid synthesis supports their phylogenetic distinctiveness from a common Demospongiae/Hexactinellida taxon. Both intraspecific and intraclass patterns of Calcarea showed great similarity, suggesting a conserved fatty acid composition that already existed in the last common ancestor of Calcinea and Calcaronea, i.e. before subclasses diverged.     

Mycosubtilins B and C: minor antibiotics from mycosubtilin-producer Bacillus subtilis

Mycosubtilins B and C were isolated from the culture medium of Bacillus subtilis. The acid hydrolysates of these new antifungal antibiotics, like mycosubtilin, contain alpha-amino acids (Asp3, Glu1, Pro1, Ser1 and Tyr1) and a mixture of iso-C16, n-C16, iso-C17 and anteiso-C17 beta-amino acids. Mycosubtilins B and C differ by the presence of a carboxyl group and of a carboxymethyl group, respectively, instead of a carboxamide group in previously described mycosubtilin.     

Fatty Acid Composition of Spirochaeta stenostrepta

The fatty acid composition of Spirochaeta stenostrepta consists primarily of saturated, branch-chained fatty acids. Iso-C(15), anteiso-C(15), iso-C(17), and anteiso-C(17) represent 66% of the total fatty acids.     

Effect of Temperature on the Fatty Acid Composition of Thermus aquaticus

Thermus aquaticus contains four major fatty acids, iso-C(15) (28%), iso-C(16) (9%), normal-C(16) (13%), and iso-C(17) (48%), when grown at 70 C, as determined by gas chromatography and mass spectrometry. Small amounts of iso-C(12), normal-C(12:1), iso-C(13), normal-C(14), iso-C(14), and normal-C(15:1) were also detected. A change in growth temperature (50 to 75 C at 5-C intervals) affects a shift in the proportions of some of the fatty acids. The proportions of the monoenoic and branched-C(17) fatty acids decreased and the proportions of the higher-melting iso-C(16) and normal-C(16) fatty acids increased. Cells grown at 75 C contained 70% more total fatty acids than cells grown at 50 C. The largest increases, in absolute amounts, were in the content of iso-C(16) and normal-C(16) fatty acids, with only a 1.6-fold increase in the major iso-C(15) and iso-C(17) fatty acids. There was a 2.5-fold decrease in normal-C(15:1) and at least a 24-fold decrease in anteiso-C(17), which is present at 50 and 55 C but not at higher temperatures. There was no difference in proportion or amount of fatty acids between exponential and stationary-phase cells grown at 70 C. When cells were grown on glutamate instead of yeast-extract and tryptone at 70 C, the total fatty acid content remained constant, but there was an increase in the proportions of iso-C(16) and normal-C(16) fatty acids concomitant with a decrease in the proportions of the iso-C(15) and iso-C(17) fatty acids.     

Isolation and characterization of an ornithine-containing lipid from Desulfovibrio gigas.

The isolation and characterization of an ornithine-containing lipid obtained from Desulfovibrio gigas are reported. The general structure for this aminolipid is represented by NH2-CH2-(CH)2-CHNH(CO-CH2CH(O-COR2)-R1)-COOH, where R1 represents 3-hydroxy palmitate linked through an amide bond to the alpha-amino group of ornithine, and R2 represents a complex variety of fatty acids esterified to the hydroxyl group of 3-hydroxy palmitate. Fatty acids characterized were n-C14:0 (21%), iso-C14:0 (14%) anteiso-C15:0 (43%), n-C16:0 (2%), n-C18:0 (8%), and n-C 18:1 (11%). The quantitative relationships between aminolipid and phospholipids showed the aminolipid to represent the major polar lipid. Isolation of the cytoplasmic and outer membranes of D. gigas showed the aminolipid to be evenly distributed between both membrane fractions, suggesting a compensatory role in phospholipid-deficient membranes.     

Bacillus nematocida sp. nov., a novel bacterial strain with nematotoxic activity isolated from soil in Yunnan, China

An endospore-forming bacterium, designated strain B-16T, was isolated from a forest soil sample in Yunnan, China. The isolate presented remarkable nematotoxic activity against nematode Panagrellus redivivus. The organism was strictly aerobic, motile, spore forming and rod shaped, catalase- and oxidase-positive. The predominant isoprenoid quinone was menaquinone 7 (MK-7). The major cellular fatty acid profiles were anteiso-C15:0 (48.67%), iso-C15:0 (13.45%), C16:0 (9.06%) and anteiso-Cl7:0 (8.29%). The DNA G+C content was 46%. Phylogenetic analyses based on 16S rDNA sequence revealed that isolate belongs to the genus Bacillus. Strain B-16T exhibited high 16S rDNA similarity with its closest neighbors Bacillus vallismortis (99.79%), B. subtilis (99.43%), B. atrophaeus (99.43%), B. amyloliquefaciens (99.36%), B. licheniformis (98.0%) and less than 97.0% with all the other relative type strains in the genus Bacillus. The phenotypic and genotypic characteristics and DNA-DNA relatedness data indicate that strain B-16T should be distinguished from all the relative species of genus Bacillus. Therefore, on the basis of the polyphasic taxonomic data presented, a new species of the genus Bacillus, B. nematocida, with the type strain B-16T ( = CGMCC 1128T) is proposed. The GenBank accession number for the sequence reported in this paper is AY820954.     

Endophytic bacillus sp. isolated from the interior of balloon flower root

A bacterial strain, designated CY22, was isolated from the interior of balloon flower (Platycodon grandiflorum) root in the Republic of Korea. The isolate coproduced an iturin-like antifungal compound and a surfactin-like potent biosurfactant. Analysis of the 16S-rDNA of strain CY22 showed that the isolate was a member of Bacillus. High similarities were observed between strain CY22 and Bacillus sp. TKSP 24, and between strain CY22 and B. subtilis 168. Phylogenetic analysis based on 16S-rDNA sequences showed that strain CY22 was closely related to Bacillus sp. The main whole-cell fatty acids were anteiso-C15:0 (37%), C17:0 (5.1%), and iso-C15:0 (27.7%). DNA G+C content was 54 mol%. Based on phylogenetic inference, phenotypic and chemotaxonomic characteristics, this endophytic strain Bacillus sp. CY22 was assigned to the genus Bacillus.     

Bacillus beringensis sp. nov., a psychrotolerant bacterium isolated from the Bering Sea

Psychrotolerant Bacillus-like strains BR035(T) and BR011 were isolated from seawater of the Bering Sea and were characterized by means of a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that these strains were related to the members of the genus Bacillus and had the highest 16S rRNA gene sequence similarity with Bacillus korlensis ZLC-26(T). DNA-DNA hybridization experiments confirmed that strains BR035(T) and BR011 belonged to the same species and were distinct from their closest relatives. The cells were Gram-positive, rods, motile, spore-forming and psychrotolerant. The temperature range for growth was 4-42°C. The main respiratory quinone was MK-7. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unknown aminolipid and two unknown phospholipids. The major cellular fatty acids were iso-C15:0, anteiso-C15:0, iso-C14:0 and C16:1ω7c alcohol. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The genomic DNA G + C content was 37.6-37.8 mol%. On the basis of the phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness data, a novel species Bacillus beringensis is proposed and the type strain is BR035(T) (=CGMCC 1.9126(T)=DSM 22571(T)).     

Microlunatus terrae sp. nov., a bacterium isolated from soil

Strain BS6(T), a Gram-positive non-motile bacterium, was isolated from soil in South Korea and characterized to determine its taxonomic position. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that strain BS6T belonged to the family Propionibacteriaceae in the class Actinobacteria. Strain BS6(T) showed the highest 16S rRNA gene sequence similarity with Microlunatus soli CC-012602(T) (98.6%) and high sequence similarities with Microlunatus species (94.5-98.6%). Chemotaxonomic data revealed that the predominant fatty acids were anteiso-C(17:0), anteiso-C(15:0), summed feature 8 (C(18:1) ω7c/ω6c), and iso-C(16:0). The cell wall peptidoglycan contained (LL)-diaminopimelic acid, and the major polar lipids were diphosphatidylglycerol, and phosphatidylglycerol. Based on these data, BS6(T) (=KCTC 19858(T) =JCM 17661(T) =CCARM 9244(T) =KEMC 9004-079(T)) should be classified as a type strain of a novel species, for which the name Microlunatus terrae sp. nov. is proposed.     

Siansivirga zeaxanthinifaciens gen. nov., sp. nov., a novel zeaxanthin-producing member of the family Flavobacteriaceae isolated from coastal seawater of Taiwan

A strictly aerobic, Gram-negative, rod-shaped bacterium (strain CC-SAMT-1(T)) showing gliding motility was isolated from coastal seawater of China Sea, Taiwan. Strain CC-SAMT-1(T) synthesizes all-trans-zeaxanthin (6.5 ± 0.5 mg g(-1) dry biomass) as a predominant xanthophyll carotenoid. As determined by 16S rRNA gene analysis, strain CC-SAMT-1(T) shared very high sequence similarity to the members of the genera Mariniflexile (96.1-95.3%) and Gaetbulibacter (96.0-95.9%); however, it formed a distinct phyletic lineage distantly associated with Mariniflexile species. Polar lipid profile constitutes phosphatidylethanolamine, four unidentified aminolipids, four unidentified lipids, and an unidentified glycolipid. Strain CC-SAMT-1(T) contains excessive unidentified aminolipid lipid (AL2-4) and glycolipid contents, and therefore clearly distinct from Mariniflexile species. Major fatty acids (> 5% of total fatty acids) were iso-C(15:0) (14.8%), iso-C(17:0) 3-OH (11.8%), iso-C(15:1) G (10.6%), anteiso-C(15:0) (9.7%), C(16:0) (8.1%), iso-C(16:0) 3-OH (7.9%), iso-C(15:0) 3-OH (7.5%), and summed feature 3 (containing C(16:1) ω6c and/or C(16:1) ω7c) (7.5%). Menaquinone-6 (MK-6) was major respiratory quinone. DNA G+C content was 33.7 mol%. Based on polyphasic taxonomy, strain CC-SAMT-1(T) represents a novel genus and species in the family Flavobacteriaceae for which the name Siansivirga zeaxanthinifaciens gen. nov., sp. nov. is proposed. The type strain is CC-SAMT-1(T) (= BCRC 80315(T) = JCM 17682(T)).     

Pseudoxanthomonas icgebensis sp. nov., isolated from the midgut of Anopheles stephensi field-collected larvae

A Gram-negative, aerobic, golden yellow, rod-shaped bacterium, a strain designated ICGEB-L15(T), was isolated from the larval midgut of Anopheles stephensi captured in District Jhajjar, Haryana, India. The strain ICGEB-L15(T) grows at 30-50°C (optimum 30-37°C), pH 6.5-8.5 (optimum 7.0-8.0) and in the presence of 2% NaCl. The major fatty acids were iso-C(15:0) (22.5% of total fatty acid), anteiso-C(15:0) (16.5%), iso-C(17:1) 9c (10.3%), iso-C(16:0) (7.3%), C(16:0) (6.1%), and iso-C(11:0) (5.3%). The strain showed the highest 16S rRNA gene sequence similarities with the type strains Pseudoxanthomonas daejeonensis KCTC 12207(T) (97.4%), Pseudoxanthomonas kaohsiungensis J36(T) (97.17%), and Pseudoxanthomonas mexicana AMX 26B(T) (97.11%). The DNA relatedness between ICGEB-L15(T) and Pseudoxanthomonas daejeonensis KCTC 12207(T), Pseudoxanthomonas kaohsiungensis J36(T) and Pseudoxanthomonas mexicana AMX 26B(T) was 24.5%, 28.2%, and 33.6%, respectively. The G+C content of genomic DNA was 69.9 mol%. The major isoprenoid quinone of strain ICGEB-L15(T) was Q-8. The strain ICGEB-L15(T) represents a novel species of the genus Pseudoxanthomonas based on physiological, biochemical and phylogenetic properties; therefore, the name Pseudoxanthomonas icgebensis sp. nov. is proposed. The type strain is ICGEB-L15(T) (=KACC 14090(T) =DSM 22536(T)).     

Factors affecting the normal and branched-chain acyl moieties of teicoplanin components produced by Actinoplanes teichomyceticus

Teicoplanin, a glycopeptide antibiotic produced by Actinoplanes teichomyceticus, comprises five main components, denoted T-A2-1 to T-A2-5, differing in the structure of their acyl side chain, which is linear in T-A2-1 and T-A2-3 and branched in the other components. Production of T-A2-1, characterized by a linear C10:1 acyl moiety, is entirely dependent on the presence of linoleate in the fermentation medium. Addition to the medium of oleic acid esters at 2 g l-1 increases the yields of T-A2-3, characterized by a linear C10:0 acyl chain, about threefold. The antibiotic linear side chains thus appear to originate from C18 unsaturated acid by beta-oxidation degradation. The percentage of T-A2-2, T-A2-4 and T-A2-5, bearing the iso-C10:0, anteiso-C11:0 and iso-C11:0 acyl moieties, respectively, is strongly influenced by the presence in the medium of the amino acids known to be precursors of branched-chain fatty acids. Thus, valine increases the production of T-A2-2 whereas isoleucine or leucine increase the relative yields of T-A2-4 or T-A2-5, respectively. Analysis of the total cell lipids upon addition of the same amino acid shows corresponding increases in the proportion of the iso-C16:0, iso-C15:0 or anteiso-C17:0. A mutant A. teichomyceticus strain, which produces a novel teicoplanin with a linear C9:0 chain, differs from the wild strain in the presence of the linear C17:1 acid in its lipids.(ABSTRACT TRUNCATED AT 250 WORDS)     

Membrane fluidity inBacillus subtilis. Validity of homeoviscous adaptation

The validity of the principle of homeoviscous adaptation for Bacillus subtilis was tested by comparing fluorescence anisotropy (1,6-diphenyl-1,3,5-hexatriene) and electron-spin resonance (16-doxylstearate) measurements carried out in isolated plasma membranes and in phospholipid fractions. The physical measurements were supplemented by fatty-acid analysis. The results support our previous findings on intact cells. The thermoadaptive mechanism of B. subtilis manifested as an increase in relative proportion of branched anteiso-C15 and anteiso-C17 fatty acids, are not strong enough to compensate for the marked physical change of membrane fluidity induced by temperature decrease.     

Luedemannella gen. nov., a new member of the family Micromonosporaceae and description of Luedemannella helvata sp. nov. and Luedemannella flava sp. nov

Three actinomycete strains were isolated from soil samples collected in Bangladesh. The cultures formed spherical sporangia on short sporangiophores directly above the surface of the substrate mycelium. The sporangia developed singly or in clusters and each sporangium contained several nonmotile spherical to oval spores with a smooth surface. The strains 3-9(24)(T), 3-21(27) and 7-40(26)(T) contained meso-diaminopimelic acid in the cell walls, predominant menaquinone MK-9(H(6)) and MK-9(H(4)) and glucose, xylose, galactose, mannose, rhamnose, ribose and arabinose in the whole-cell hydrolysates. Diagnostic phospholipid is phosphatidylethanolamine and branched anteiso-C(17 : 0) (30.0-38.0%), anteiso-C(15 : 0) (12.5-14.0%), iso-C(16 : 0) (10.0-15.0%) and iso-C(15 : 0) (10.0-12.0%) were detected as the major cellular fatty acids. The acyl type of the peptidoglycan was glycolyl and mycolic acids were not detected. The G+C content of the DNA was 71 mol%. The chemotaxonomic data indicate that these strains belong to the family Micromonosporaceae. Phylogenetic analysis based on 16S rRNA gene sequence data suggested that the strains 3-9(24)(T), 3-21(27) and 7-40(26)(T) fall within the family Micromonosporaceae. On the basis of phylogenetic analysis and characteristic patterns of signature nucleotides as well as morphological and chemotaxonomic data, Luedemannella gen. nov. is proposed for our 3 isolates. DNA-DNA hybridization experiment and phenotypic characterization indicated that the new genus was constituted of 2 species, as Luedemannella helvata sp. nov. for the strain 3-9(24)(T) (=JCM 13249(T)=MTCC 8091(T)) and Luedemannella flava for the strain 7-40(26)(T) (=JCM 13250(T)=MTCC 8095(T)) in the family Micromonosporaceae.     

Composition of human serum sphingomyelins

Serum sphingomyelins were analyzed by argentation chromatography of the corresponding ceramide diacetates. Six subfractions were obtained. Three of them contained 4-sphingenines in combination with saturated, trans-, or cis-monoenoic fatty acids; the remaining three contained sphingadienine, also in combination with saturated, trans-, or cis-monoenoic fatty acids. Palmitic acid was the principal fatty acid combined with 4-sphingenines, while nervonic acid was the principal fatty acid combined with sphingadienine. About 4% of the total fatty acids of sphingomyelin were trans-monoenoic. They were comprised of many positional isomers of straight-chain C(22-24) compounds. The cis-monoenoic acids made up 33% of the total acids and consisted of almost pure nervonic acid. The rest of the acids were saturated. The 4-sphingenines contained small amounts of iso-C(18) and anteiso-C(19) compounds in addition to the straight-chain C(16-18) bases.     

Characterization of Exiguobacterium isolates from the Siberian permafrost. Description of Exiguobacterium sibiricum sp. nov.

Three Gram-positive bacterial strains, 7-3, 255-15 and 190-11, previously isolated from Siberian permafrost, were characterized and taxonomically classified. These microorganisms are rod-shaped, facultative aerobic, motile with peritrichous flagella and their growth ranges are from -2.5 to 40 degrees C. The chemotaxonomic markers indicated that the three strains belong to the genus Exiguobacterium. Their peptidoglycan type was A3alpha L-Lys-Gly. The predominant menaquinone detected in all three strains was MK7. The polar lipids present were phosphatidyl-glycerol, diphosphatidyl-glycerol and phosphatidyl-ethanolamine. The major fatty acids were iso-C13:0, anteiso-C13:0, iso-C15:0, C16:0 and iso-C17:0. Phylogenetic analysis based on 16S rRNA and six diverse genes, gyrB (gyrase subunit B), rpoB (DNA-directed RNA polymerase beta subunit), recA (homologous recombination), csp (cold shock protein), hsp70 (ClassI-heat shock protein-chaperonin) and citC (isocitrate dehydrogenase), indicated that the strains were closely related to Exiguobacterium undae (DSM 14481(T)) and Exiguobacterium antarcticum (DSM 14480(T)). On the basis of the phenotypic characteristics, phylogenetic data and DNA-DNA reassociation data, strain 190-11 was classified as E. undae, while the other two isolates, 7-3 and 255-15, comprise a novel species, for which the name Exiguobacterium sibiricum sp. nov. is proposed.     

Cold shock response of Bacillus subtilis: isoleucine-dependent switch in the fatty acid branching pattern for membrane adaptation to low temperatures.

Bacillus subtilis has developed sophisticated mechanisms to withstand fluctuations in temperature. Membrane fatty acids are the major determinants for a sufficiently fluid membrane state to ensure the membrane's function at all temperatures. The fatty acid profile of B. subtilis is characterized by a high content of branched fatty acids irrespective of the growth medium. Here, we report on the importance of isoleucine for B. subtilis to survive cold shock from 37 to 15 degrees C. Cold shock experiments with strain JH642 revealed a cold-protective function for all intermediates of anteiso-branched fatty acid biosynthesis. Metabolites related to iso-branched or straight-chain fatty acid biosynthesis were not protective. Fatty acid profiles of different B. subtilis wild-type strains proved the altered branching pattern by an increase in the anteiso-branched fatty acid content and a concomitant decrease of iso-branched species during cold shock. There were no significant changes in the fatty acid saturation or acyl chain length. The cold-sensitive phenotype of isoleucine-deficient strains in the absence of isoleucine correlated with their inability to synthesize more anteiso-branched fatty acids, as shown by the fatty acid profile. The switch to a fatty acid profile dominated by anteiso-C(15:0) and C(17:0) at low temperatures and the cold-sensitive phenotype of isoleucine-deficient strains in the absence of isoleucine focused our attention on the critical role of anteiso-branched fatty acids in the growth of B. subtilis in the cold.     

Leucobacter exalbidus sp. nov., an actinobacterium isolated from a mixed culture from compost

A gram-positive bacterium, strain K-540B(T), which was separated from a mixed culture isolated from compost, was subjected to a polyphasic taxonomic study. Strain K-540B(T) was found to have 95.5%-98.7% sequence similarity with the genus Leucobacter based on 16S rRNA gene sequence analyis. Phenotypic and chemical properties of strain K-540B(T) were consistent with its classification in the genus Leucobacter. The major quinone system compound was MK-11 and major fatty acids were anteiso-C(15:0) and iso-C(16:0). Polar lipids included phosphatidylglycerol and diphosphatidylglycerol. The G+C content of the genomic DNA was 64.9 mol%. The cell wall peptidoglycan contained diaminobutyric acid and γ-aminobutyric acid. DNA-DNA hybridization results and physiological tests genotypically and phenotypically differentiated strain K-540B(T) from other Leucobacter species. Based on these results, strain K-540B(T) (=NBRC 106062(T)=DSM 22850(T)), for which the name Leucobacter exalbidus sp. nov. is proposed, represents a novel species of the genus Leucobacter.     

Bacillus zhanjiangensis sp. nov., isolated from an oyster in South China Sea

A novel Gram-stain-positive, motile, catalase- and oxidase-positive, endospore-forming, aerobic, rod-shaped bacterium, designated strain JSM 099021^T, was isolated from an oyster collected from Naozhou Island in the South China Sea. Growth occurred with 0?C15% (w/v) NaCl (optimum 2?C4%) and at pH 6.0?C10.0 (optimum pH 7.5) and at 10?C45°C (optimum 30?C35°C). meso-Diaminopimelic acid was present in the cell-wall peptidoglycan. The predominant respiratory quinone was menaquinone 7 (MK-7) and the major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The major cellular fatty acids were anteiso-C15:0, anteiso-C17:0, iso-C15:0 and iso-C16:0. The genomic DNA G + C content was 39.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 099021^T belongs to the genus Bacillus, and was most closely related to the type strains of Bacillus halmapalus (sequence similarity 99.0%), Bacillus horikoshii (98.4%) and Bacillus cohnii (98.0%). The combination of phylogenetic analysis, DNA?CDNA hybridization, phenotypic characteristics and chemotaxonomic data supported the proposal that strain JSM 099021^T represents a new species of the genus Bacillus, for which the name Bacillus zhanjiangensis sp. nov. is proposed. The type strain was JSM 099021^T (=DSM 23010^T = KCTC 13713^T).
