A Gram-reaction-negative, rod-shaped marine bacterium, designated MEBiC08158T, was isolated from sediments collected from Taean County, Korea, near the Hebei Spirit tanker oil spill accident. 16S rRNA gene sequence analysis revealed that strain MEBiC08158T was closely related to Alcanivorax marinus R8-12T (99.5 % similarity) but was distinguishable from other members of the genus Alcanivorax (93.7–97.1 %). The DNA–DNA hybridization value between strain MEBiC08158T and A. marinus R8-12T was 58.4 %. Growth of strain MEBiC08158T was observed at 15–43 °C (optimum 37–40 °C), at pH 6.0–9.5 (optimum pH 7.0–8.0) and with 0.5–16 % NaCl (optimum 1.5–3.0 %). The dominant fatty acids were C16 : 0, C19 : 0 cyclo ω8c, C12 : 0, C18 : 1ω7c, C12 : 0 3-OH and summed feature 3 (comprising C15 : 0 2-OH and/or C16 : 1ω7c). Several phenotypic characteristics differentiate strain MEBiC08158T from phylogenetically close members of the genus Alcanivorax. Therefore, strain MEBiC08158T should be classified as representing a novel species of the genus Alcanivorax, for which the name Alcanivorax gelatiniphagus sp. nov. is proposed. The type strain is MEBiC08158T ( = KCCM 42990T = JCM 18425T).

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).

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).

An endospore-forming strain, 20CMT, was isolated from Antarctic sediment and identified as a member of the genus Paenibacillus on the basis of phenotypic and phylogenetic analyses. The organism stained Gram-variable and was facultatively anaerobic. Strain 20CMT was psychrotolerant, growing optimally at 10–15 °C. Like other Paenibacillus species, it contained anteiso-C15 : 0 as the major cellular fatty acid. The DNA G+C content was 40·7 mol%. 16S rRNA gene sequence analysis placed strain 20CMT within the Paenibacillus cluster, with a similarity value of 99·5 % to Paenibacillus macquariensis DSM 2T. DNA–DNA hybridization experiments between the Antarctic isolate and P. macquariensis DSM 2T revealed a reassociation value of 47 %, indicating that strain 20CMT and P. macquariensis DSM 2T belong to different species. Based on evaluation of morphological, physiological, chemotaxonomic and phylogenetic analyses, a novel species, Paenibacillus antarcticus sp. nov., is proposed; the type strain is 20CMT (=LMG 22078T=CECT 5836T).

A Gram-negative, non-spore-forming, rod-shaped bacterium, designated strain DCY01T, was isolated from soil from a ginseng field in South Korea and was characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain DCY01T belonged to the Gammaproteobacteria and was most closely related to Stenotrophomonas koreensis KCTC 12211T (98.4 % similarity), Stenotrophomonas humi R-32729T (97.2 %), Stenotrophomonas terrae R-32768 (97.1 %), Stenotrophomonas maltophilia DSM 50170T (96.9 %) and Stenotrophomonas nitritireducens DSM 12575T (96.8 %). Chemotaxonomic analyses revealed that strain DCY01T possessed a quinone system with Q-8 as the predominant compound, and iso-C15 : 0 (28.2 %), C16 : 0 10-methyl (13.2 %), iso-C15 : 1 F (10.8 %) and C15 : 0 (7.5 %) as major fatty acids, corroborating assignment of strain DCY01T to the genus Stenotrophomonas. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain DCY01T represents a species distinct from recognized Stenotrophomonas species. Based on these data, DCY01T (=KCTC 12539T=NBRC 101154T) should be classified as the type strain of a novel species of the genus Stenotrophomonas, for which the name Stenotrophomonas ginsengisoli sp. nov. is proposed.

Thirty-one bacteria that belonged to the genus Pseudomonas were isolated from cyanobacterial mat samples that were collected from various water bodies in Antarctica. All 31 isolates were psychrophilic; they could be divided into three groups, based on their protein profiles. Representative strains of each of the three groups, namely CMS 35T, CMS 38T and CMS 64T, were studied in detail. Based on 16S rRNA gene sequence analysis, it was established that the strains were related closely to the Pseudomonas fluorescens group. Phenotypic and chemotaxonomic characteristics further confirmed their affiliation to this group. The three strains could also be differentiated from each other and the closely related species Pseudomonas orientalis, Pseudomonas brenneri and Pseudomonas migulae, based on phenotypic and chemotaxonomic characteristics and the level of DNA–DNA hybridization. Therefore, it is proposed that strains CMS 35T (=MTCC 4992T=DSM 15318T), CMS 38T (=MTCC 4993T=DSM 15319T) and CMS 64T (=MTCC 4994T=DSM 15321T) should be assigned to novel species of the genus Pseudomonas as Pseudomonas antarctica sp. nov., Pseudomonas meridiana sp. nov. and Pseudomonas proteolytica sp. nov., respectively.

A novel, Gram-stain-positive, non-motile, facultatively anaerobic, rod- or coccoid-shaped bacterium, designated strain ORY33T, was isolated from the gut of a camel cricket (Diestrammena coreana). The 16S rRNA gene sequence analysis showed that strain ORY33T belonged to the genus Weissella , with highest sequence similarity to Weissella koreensis S-5623T (97.7 %). The strain grew optimally at 30 °C and pH 7 in the presence of 0 % (w/v) NaCl. Catalase and oxidase activities were negative. The genomic DNA G+C content of strain ORY33T was 45.1 mol%. DNA–DNA hybridization values between strain ORY33T and closely related members of the genus Weissella were less than 27 %. The major fatty acids of strain ORY33T were C18 : 1ω9c, C16 : 0 and C14 : 0. Based on these phenotypic, phylogenetic and genotypic analyses, strain ORY33T represents a novel species belonging to the genus Weissella , for which the name Weissella diestrammenae sp. nov. is proposed. The type strain is ORY33T ( = KACC 16890T = JCM 18559T).

An arsenite-oxidizing bacterium, designated strain ULPAs1T, was isolated from industrial sludge heavily contaminated with arsenic. Cells of this isolate were Gram-negative, curved rods, motile by means of a polar flagellum. The strain was positive for oxidase and catalase activities, was able to reduce nitrate to nitrite, used acetate, lactate and peptone as organic carbon sources under aerobic conditions and was able to oxidize arsenite (As[III]) to arsenate (As[V]). 16S rRNA gene sequence analysis and the absence of dodecanoic fatty acids suggested that this strain represents a member of the genus Herminiimonas of the family Oxalobacteraceae, order Burkholderiales in the Betaproteobacteria. Genomic DNA–DNA hybridization between strain ULPAs1T and Herminiimonas fonticola S-94T and between strain ULPAs1T and Herminiimonas aquatilis CCUG 36956T revealed levels of relatedness of <10 %, well below the recommended 70 % species cut-off value. Thus, strain ULPAs1T (=CCM 7303T=DSM 17148T=LMG 22961T) is the type strain of a novel species of Herminiimonas, for which the name Herminiimonas arsenicoxydans sp. nov. is proposed.

The phenotypic and phylogenetic characteristics of an aerobic, Gram-negative, motile, non-pigmented Alteromonas-like bacterium (designated strain KMM 3894T), isolated from a sandy sediment sample collected offshore of the Sea of Japan, were investigated. Comparative 16S rRNA gene sequence analysis revealed that strain KMM 3894T belonged to the genus Aestuariibacter and was most closely related to Aestuariibacter halophilus JC2043T (95.5 % sequence similarity). Fatty acid analysis showed C16 : 1 ω7c, C18 : 1 ω7c, and C16 : 0 as the dominant components. Strain KMM 3894T could be differentiated from recognized species of the genus Aestuariibacter by its ability to grow at 4 °C and at 30 °C, the optimum temperature for growth, and its inability to utilize most carbohydrates. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain KMM 3894T is considered to represent a novel species of the genus Aestuariibacter, for which the name Aestuariibacter litoralis sp. nov. is proposed. The type strain is KMM 3894T (=NRIC 0754T=JCM 15896T).

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).
