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).

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%.

Two novel actinobacteria isolates, designated YIM 70009T and YIM 70081T, were characterized in order to determine their taxonomic position. Cells of strains YIM 70009T and YIM 70081T were cocci, although only the latter were motile. The G+C contents of their DNAs were 64·0 and 64·5 mol%, respectively. On the basis of chemotaxonomic characteristics and 16S rRNA gene sequence analysis, the two isolates were classified in the genus Nesterenkonia. DNA–DNA hybridization and comparison of phenotypic characteristics revealed that strains YIM 70009T and YIM 70081T differed from each other and from known species. Therefore, it is proposed that they represent two separate novel species of the genus Nesterenkonia: Nesterenkonia sandarakina sp. nov. (type strain, YIM 70009T=CCTCC AA 203007T=DSM 15664T=KCTC 19011T) and Nesterenkonia lutea sp. nov. (type strain, YIM 70081T=CCTCC AA 203010T=DSM 15666T=KCTC 19013T).

Gene Sequence Analysis

The taxonomic position of a bacterium isolated from a cold desert of the Himalayas, India, was analysed by using a polyphasic approach. The isolated strain, designated K22-03T, had phenotypic characteristics that matched those of the genus Planococcus and it represents a novel species. The almost-complete 16S rRNA gene sequence (1464 bases) of the novel strain was compared with those of previously studied Planococcus type strains and confirmed that the strain belongs to the genus Planococcus. 16S rRNA gene sequence analysis indicated that strain K22-03T differs from all other species of Planococcus by at least 2·5 %. DNA–DNA hybridization showed that it had low genomic relatedness with Planomicrobium mcmeekinii (MTCC 3704T, 23 %), Planococcus psychrophilus (MTCC 3812T, 61 %), Planococcus antarcticus (MTCC 3854T, 45 %) and Planomicrobium okeanokoites (MTCC 3703T, 51 %), the four species with which it was most closely related based on 16S rRNA gene sequence analysis (97–97·5 % similarity). Therefore, strain K22-03T should be recognized as a novel species, for which the name Planococcus stackebrandtii sp. nov. is proposed. The type strain is K22-03T (=MTCC 6226T=DSM 16419T=JCM 12481T).

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).

A novel bacterium, designated strain HT27T, was isolated from a sulfur spring sample collected from Athamallik, Orissa, India, and was characterized by using a polyphasic approach. Cells were Gram-negative, strictly aerobic, rod-shaped and motile by means of a single polar flagellum. Strain HT27T was oxidase- and catalase-positive. Growth was observed at pH 5.0–11.0 and at 15–45 °C; the highest growth yield was observed at pH 7.5–8.0 and 30–37 °C. The G+C content of the genomic DNA of strain HT27T was 63 mol%. The major cellular fatty acids were C16 : 1 ω7c (44.24 %), C16 : 0 (27.65 %), C18 : 1 ω7c (13.98 %), C12 : 0 (2.60 %) and C12 : 0 3-OH (2.22 %). 16S rRNA gene sequence analysis indicated that strain HT27T clustered with the genus Gulbenkiania and showed 99.0 % similarity to Gulbenkiania mobilis E4FC31T. However, the level of DNA–DNA relatedness between strain HT27T and G. mobilis E4FC31T was 30 %. On the basis of phenotypic and chemotaxonomic characteristics, 16S rRNA gene sequence analysis and DNA–DNA hybridization data, strain HT27T is considered to represent a novel species of the genus Gulbenkiania, for which the name Gulbenkiania indica sp. nov. is proposed. The type strain is HT27T (=DSM 17901T =JCM 15969T).

A Gram-negative bacterium, designated KIS13-15T, was isolated from soil in Korea. Cells were strictly aerobic rods and were motile with 1–3 subpolar flagella. 16S rRNA gene sequence analysis revealed that strain KIS13-15T belonged to the order Xanthomonadales of the class Gammaproteobacteria and was closely related to Nevskia soli GR15-1T (97.9 % 16S rRNA gene sequence similarity) and Nevskia ramosa Soe1T (96.8 %). Strain KIS13-15T exhibited 38 and 29 % DNA–DNA relatedness with N. soli KACC 11703T and N. ramosa DSM 11499T, respectively. The major fatty acids (>10 % of the total) were C18 : 1ω7c (40.6 %) and C16 : 0 (12.4 %). The major isoprenoid quinone was ubiquinone 8. DNA G+C content was 67.3 mol%. The phenotypic characterization combined with 16S rRNA gene sequence analysis and DNA–DNA hybridization clearly classified strain KIS13-15T in a novel species of the genus Nevskia, for which the name Nevskia terrae sp. nov. is proposed. The type strain is KIS13-15T ( = KACC 12736T  = JCM 15425T).

Sequence Similarities

Seventeen anaerobic, Gram-negative, tiny coccobacilli were collected in France from various human clinical samples. Biochemical analyses as well as molecular studies, including 16S rRNA and dnaK gene sequencing, affiliated all the isolates to the genus Dialister. However, 16S rRNA and dnaK gene sequence similarities were below 95·2 and 79·7 %, respectively, when comparisons were performed with the currently described species Dialister pneumosintes and Dialister invisus. Two clusters consisting of 13 and four isolates could be differentiated. 16S rRNA- and dnaK-based phylogeny confirmed that these two clusters represent two novel and distinct lineages within the genus Dialister. Finally, phenotypic, genotypic and phylogenetic data supported the proposal of the two novel species Dialister micraerophilus sp. nov. (type strain ADV 04.01T=AIP 25.04T=CIP 108278T=CCUG 48837T) and Dialister propionicifaciens sp. nov. (type strain ADV 1053.03T=AIP 26.04T=CIP 108336T=CCUG 49291T). The G+C content of the DNA of the D. micraerophilus type strain is 36·3 mol%. On the basis of 16S rRNA gene sequence analysis, 11 isolates originating from Canada could also be affiliated to D. micraerophilus sp. nov., and were included in the species description.
