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).

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).

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).

The taxonomic position of a novel marine, heterotrophic, gliding, halotolerant and light-pink-pigmented bacterium, designated strain KMM 6221T, was examined by using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain KMM 6221T is affiliated with the genus Echinicola, a member of the phylum Bacteroidetes, with levels of similarity of 94.7–95.0 % to strains of Echinicola pacifica. Growth of strain KMM 6221T was observed with 0–15 % NaCl and at 6–44 °C. The DNA G+C content of strain KMM 6221T was 45.9 mol%. On the basis of molecular distinctiveness supported by phenotypic and chemotaxonomic data, strain KMM 6221T is considered to represent a novel species of the genus Echinicola, for which the name Echinicola vietnamensis sp. nov. is proposed. The type strain is KMM 6221T (=DSM 17526T=LMG 23754T).

Three strains of anaerobic Gram-negative bacilli isolated from human oral sites were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. 16S rRNA gene sequence analysis revealed the strains to constitute a novel group within the genus Prevotella, most closely related to Prevotella oris and Prevotella salivae. A novel species, Prevotella maculosa sp. nov., is proposed to accommodate these strains. Prevotella maculosa is saccharolytic and produces acetic and succinic acids as end products of fermentation. The G+C content of the DNA of the type strain is 48 mol%. The type strain of Prevotella maculosa is W1609T (=DSM 19339T =CCUG 54766T).

An ivory-coloured bacterium, designated strain 5YN7-3T, was isolated from a wetland, Yongneup, Korea. Cells of the strain were aerobic, Gram-stain-negative, non-motile and short rods. 16S rRNA gene sequence analysis demonstrated that strain 5YN7-3T belongs to the order Rhizobiales of the class Alphaproteobacteria and is closely related to Kaistia soli 5YN9-8T (97.8 %), Kaistia granuli Ko04T (97.6 %) and Kaistia adipata Chj404T (97.4 %). Strain 5YN7-3T showed DNA–DNA hybridization values of 28, 22 and 35 % with K. granuli Ko04T, K. soli 5YN9-8T and K. adipata Chj404T, respectively. The major fatty acids were C18 : 1 ω7c (51.2 %), C19 : 0 cyclo ω8c (25.0 %), C18 : 0 (12.9 %) and C16 : 0 (10.8 %) (>10 % of total fatty acids). Ubiquinone-10 was the major isoprenoid quinone and the DNA G+C content was 66.5 mol%. The phenotypic characteristics in combination with 16S rRNA gene sequence analysis and DNA–DNA hybridization data clearly define strain 5YN7-3T as a novel species of the genus Kaistia, for which the name Kaistia terrae sp. nov. is proposed. The type strain is 5YN7-3T (=KACC 12910T =DSM 21341T).

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).

A novel Gram-staining-positive, rod-shaped bacterium, designated DCY100T, was isolated from rhizome of mountain ginseng root in Hwacheon mountain, Gangwon province, Republic of Korea. The 16S rRNA gene sequence analysis showed that strain DCY100T belonged to the genus Microbacterium and was most closely related to Microbacterium ginsengisoli KCTC 19189T (97.9 %), Microbacterium lacus JCM 15575T (97.2 %) and Microbacterium invictum DSM 19600T (97.1 %). The major menaquinones were MK-11 and MK-12. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid. The major fatty acids (>10.0 %) were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The cell-wall peptidoglycan contained the amino acids ornithine, alanine, glutamic acid and glycine; whole-cell sugars consisted of glucose, galactose, rhamnose and ribose. The DNA G+C content was 63.6 ± 0.7 mol%. The DNA–DNA hybridization relatedness values between strain DCY100T and Microbacterium ginsengisoli KCTC 19189T, Microbacterium lacus JCM 15575T and Microbacterium invictum DSM 19600T were 36.2 ± 0.4, 22.0 ± 3.0 and 15.3 ± 1.8 %, respectively. On the basis of phenotypic, chemotaxonomic and genotypic analyses, the isolate is classified as a representative of a novel species in the genus Microbacterium, for which the name Microbacterium rhizomatis DCY100T is proposed. The type strain is DCY100T ( = KCTC 39529T = JCM 30598T).

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).
