Gene Sequence Analysis

The taxonomic position of strain JCM 2765T isolated from fermented cane molasses in Thailand was reinvestigated. Strain JCM 2765T was originally identified as representing Lactobacillus buchneri on the basis of biochemical and physiological characteristics. In the present study, 16S rRNA gene sequence analysis of strain JCM 2765T demonstrated a low level of similarity with the type strain of L. buchneri (92.5 %) and high levels with those of Lactobacillus collinoides (97.6 %) and Lactobacillus paracollinoides (98.0 %). Ribotyping was applied to investigate the relationships between strain JCM 2765T, L. collinoides and L. paracollinoides. The dendrogram based on ribotyping patterns showed one cluster for six strains of L. paracollinoides, and that strain JCM 2765T and L. collinoides JCM 1123T were each independent. Based on additional phenotypic findings and DNA–DNA hybridization results, strain JCM 2765T is considered to represent a novel species of the genus Lactobacillus, for which the name Lactobacillus similis sp. nov. is proposed. The type strain is JCM 2765T (=LMG 23904T).

Gene Sequence Analysis

Sixty-two strains of thermophilic aerobic endospore-forming bacteria were subjected to polyphasic taxonomic study including 16S rRNA gene sequence analysis, polar lipid and fatty acid analysis, phenotypic characterization, and DNA–DNA hybridization experiments. Distinct clusters of the species Geobacillus stearothermophilus , Geobacillus thermodenitrificans , Geobacillus toebii and Geobacillus thermoglucosidasius were formed, allowing their descriptions to be emended, and the distinctiveness of the poorly represented species Geobacillus jurassicus , Geobacillus subterraneus and Geobacillus caldoxylosilyticus was confirmed. It is proposed that the name Geobacillus thermoglucosidasius be corrected to Geobacillus thermoglucosidans nom. corrig. Bacillus thermantarcticus clustered between Geobacillus species on the basis of 16S rRNA gene sequence analysis, and its transfer to the genus Geobacillus as Geobacillus thermantarcticus comb. nov. (type strain LMG 23032T = DSM 9572T = strain M1T = R-35644T) is proposed. The above-mentioned species, together with Geobacillus thermoleovorans and Geobacillus thermocatenulatus , form a monophyletic cluster representing the genus Geobacillus . The distinctiveness of ‘Geobacillus caldoproteolyticus’ was confirmed and it is proposed that it be accommodated, along with Geobacillus tepidamans , in the genus Anoxybacillus as Anoxybacillus caldiproteolyticus sp. nov. (type strain DSM 15730T = ATCC BAA-818T = LMG 26209T = R-35652T) and Anoxybacillus tepidamans comb. nov. (type strain LMG 26208T = ATCC BAA-942T = DSM 16325T = R-35643T), respectively. The type strain of Geobacillus debilis was not closely related to any members of the genera Anoxybacillus and Geobacillus , and it is proposed that this species be placed in the new genus Caldibacillus as Caldibacillus debilis gen. nov. comb. nov. The type strain of the type species, Caldibacillus debilis, is LMG 23386T ( = DSM 16016T = NCIMB 13995T = TfT = R-35653T).

Gram Positive Cocci

Seven strains of anaerobic Gram-positive cocci isolated from human oral sites were subjected to a comprehensive range of phenotypic and genotypic tests. 16S rRNA gene sequence analysis revealed that the strains constituted a homogeneous group that was distinct from species with validly published names, but related to Peptostreptococcus anaerobius. All oral strains tested belonged to this group, whereas all non-oral strains studied were confirmed as P. anaerobius. A novel species, Peptostreptococcus stomatis sp. nov., is proposed to accommodate these oral strains. P. stomatis is weakly saccharolytic and produces acetic, butyric, isobutyric, isovaleric and isocaproic acids as end products of fermentation. The type strain of P. stomatis is W2278T (=DSM 17678T=CCUG 51858T); the G+C content of the DNA of this strain is 36 mol%.

Gene Sequence Analysis

A Gram-positive, rod-shaped, endospore-forming organism, strain CCUG 47242T, was isolated from a sample of industrial starch production in Sweden. 16S rRNA gene sequence analysis demonstrated that this isolate was moderately related to species of the genus Paenibacillus, with <94·4 % sequence similarity to all other hitherto described Paenibacillus species. Strain CCUG 47242T showed the greatest sequence similarity (96·5 %) to ‘Paenibacillus hongkongensis’ HKU3, a strain with a name that has not yet been validly published. Chemotaxonomic data [major menaquinone, MK-7 (98 %); major polar lipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lysyl-phosphatidylglycerol, two unknown phospholipids, four unknown aminophospholipids; major fatty acids, iso-C16 : 0 and anteiso-C15 : 0] showed some significant differences when compared with the type species of the genus Paenibacillus, Paenibacillus polymyxa. Physiological and biochemical tests allowed clear phenotypic differentiation of strain CCUG 47242T from strain HKU3. On the basis of 16S rRNA gene sequence analysis, in combination with chemotaxonomic data, strains CCUG 47242T and HKU3 represent two novel species of a new genus of endospore-forming bacteria for which we propose the names Cohnella thermotolerans gen. nov., sp. nov. (type strain CCUG 47242T=CIP 108492T=DSM 17683T) and Cohnella hongkongensis sp. nov. (type strain HKU3T=CCUG 49571T=CIP 107898T=DSM 17642T).

Gene Sequence Analysis

A Gram-stain-negative bacterial strain, 10-17T, was isolated from traditional sourdough in Heilongjiang Province, China. The bacterium was characterized by a polyphasic approach, including 16S rRNA gene sequence analysis, RNA polymerase β subunit (rpoB) gene sequence analysis, DNA gyrase (gyrB) gene sequence analysis, initiation translation factor 2 (infB) gene sequence analysis, ATP synthase β subunit (atpD) gene sequence analysis, fatty acid methyl ester analysis, determination of DNA G+C content, DNA–DNA hybridization and an analysis of phenotypic features. Strain 10-17T was phylogenetically related to Enterobacter hormaechei CIP 103441T, Enterobacter cancerogenus LMG 2693T, Enterobacter asburiae JCM 6051T, Enterobacter mori LMG 25706T, Enterobacter ludwigii EN-119T and Leclercia adecarboxylata LMG 2803T, having 99.5 %, 99.3 %, 98.7 %, 98.5 %, 98.4 % and 98.4 % 16S rRNA gene sequence similarity, respectively. On the basis of polyphasic characterization data obtained in the present study, a novel species, Enterobacter xiangfangensis sp. nov., is proposed and the type strain is 10-17T ( = LMG 27195T = NCIMB 14836T = CCUG 62994T). Enterobacter sacchari Zhu et al. 2013 was reclassified as Kosakonia sacchari comb. nov. on the basis of 16S rRNA, rpoB, gyrB, infB and atpD gene sequence analysis and the type strain is strain SP1T( = CGMCC 1.12102T = LMG 26783T).

Gene Sequence Analysis

An aerobic, Gram-negative, rod-shaped bacterium with polar flagella, strain CC-AFH3T, was isolated from an oil-contaminated site located in Kaohsiung county, Taiwan. Strain CC-AFH3T grew at 20–40 °C, pH 5.0–10.0 and <2 % (w/v) NaCl. 16S rRNA gene sequence analysis indicated that strain CC-AFH3T showed the greatest degree of similarity to Herbaspirillum soli SUEMI10T (96.5 %), H. aurantiacum SUEMI08T (96.3 %), H. canariense SUEMI03T (96.0 %), H. psychrotolerans PB1T (95.4 %) and members of other Herbaspirillum species (94.1–95.2 %), and lower similarity to members of other genera (<94 %). Phylogenetic analyses also positioned the novel strain in the genus Herbaspirillum as an independent lineage. The major fatty acids in strain CC-AFH3T were C10 : 0 3-OH, C12 : 0, C14 : 0 2-OH, C16 : 0, iso-C15 : 0 3-OH, C17 : 0 cyclo, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c. The major polar lipids of strain CC-AFH3T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The predominant quinone was ubiquinone 8 (Q-8) and the DNA G+C content was 63.4 mol%. On the basis of 16S rRNA gene sequence analysis in combination with physiological and chemotaxonomic data, strain CC-AFH3T represents a novel species in a new genus, for which we propose the name Noviherbaspirillum malthae gen. nov., sp. nov.; the type strain of Noviherbaspirillum malthae is CC-AFH3T ( = BCRC 80516T = JCM 18414T). We also propose the reclassification of Herbaspirillum soli , Herbaspirillum aurantiacum , Herbaspirillum canariense and ‘Herbaspirillum psychrotolerans’ as Noviherbaspirillum soli comb. nov. (type strain SUEMI10T = LMG 26149T = CECT 7840T), Noviherbaspirillum aurantiacum comb. nov. (type strain SUEMI08T = LMG 26150T = CECT 7839T), Noviherbaspirillum canariense comb. nov. (type strain SUEMI03T = LMG 26151T = CECT 7838T) and Noviherbaspirillum psychrotolerans comb. nov. (type strain PB1T = DSM 26001T = LMG 27282T), respectively. An emended description of Herbaspirillum seropedicae is also presented.

Gene Sequence Analysis

A cream-coloured, Gram-stain-negative, aerobic, non-motile, rod- to irregular shaped bacterium, strain 119/4T, was isolated from a choana swab of a white stork nestling on sheep blood agar. 16S rRNA gene sequence analysis and subsequent comparisons showed that it was a member of the family Rhodobacteraceae, showing 94.9 % similarity to the type strain of Gemmobacter tilapiae and 94.6 % similarity to that of Gemmobacter nectariphilus , but also similarly low sequence similarity to the type strains of Rhodobacter viridis (94.8 %), Rhodobacter veldkampii (94.6 %) and Paenirhodobacter enshiensis (94.6 %). Reconstruction of phylogenetic trees showed that strain 119/4T clustered close to species of the genus Gemmobacter . The quinone system contained high amounts of ubiquinone Q-10 with traces of Q-8, Q-9 and Q-11, and the fatty acid profile consisted mainly of C18 : 1ω7c, C16 : 1ω7c/iso-C15 : 0 2-OH and C10 : 0 3-OH. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phoshatidylglycerol and phosphatidylcholine. Major polyamines were putrescine and spermidine. On the basis of 16S rRNA gene sequence analysis and chemotaxonomic and physiological data, strain 119/4T represents a novel species of the genus Gemmobacter , for which the name Gemmobacter intermedius sp. nov. is proposed. The type strain is 119/4T ( = CIP 110795T = LMG 28215T = CCM 8510T).

The taxonomic positions of ‘Renobacter vacuolatum’ DSM 1277 and ‘Ancylobacter polymorphus’ DSM 2457 were investigated in this study. 16S rRNA gene sequence analysis indicated that both strains belonged to the genus Ancylobacter. DNA–DNA hybridization showed that they differed from Ancylobacter aquaticus DSM 101T and Ancylobacter rudongensis AS 1.1761T. According to molecular and phenotypic characteristics, strain DSM 1277T (=AS 1.2807T) is proposed as the type strain of Ancylobacter vacuolatus sp. nov. At the same time, valid publication of the name Ancylobacter polymorphus sp. nov. is proposed, with the type strain DSM 2457T (=AS 1.2800T=NCIMB 10516T).
