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).

Among a large collection of Taiwanese soil isolates, a novel Gram-variable, rod-shaped, motile and endospore-forming bacterial strain, designated G-soil-2-3T, was isolated from farmland soil in Wu-Feng, Taiwan. The isolate was subjected to a polyphasic study including 16S rRNA gene sequence analysis, DNA–DNA hybridization experiments, fatty acid analysis and comparative phenotypic characterization. 16S rRNA gene sequence analysis indicated that the organism belongs within the genus Paenibacillus. It contained menaquinone MK-7 as the predominant isoprenoid quinone and anteiso-C15 : 0 (40.5 %), iso-C15 : 0 (13.1 %), iso-C16 : 0 (10.8 %) and anteiso-C17 : 0 (7.3 %) as the major fatty acids. Phylogenetically, the closest relatives of strain G-soil-2-3T were the type strains of Paenibacillus assamensis, Paenibacillus alvei and Paenibacillus apiarius, with 16S rRNA gene sequence similarity of 95.7, 95 and 95.2 %, respectively. DNA–DNA hybridization experiments showed levels of relatedness of 2.8–9.0 % of strain G-soil-2-3T with these strains. The G+C content of the DNA was 44.6 mol%. Strain G-soil-2-3T was clearly distinguishable from P. assamensis, P. alvei and P. apiarius and thus represents a novel species of the genus Paenibacillus, for which the name Paenibacillus taiwanensis sp. nov. is proposed. The type strain is G-soil-2-3T (=BCRC 17411T=IAM 15414T=LMG 23799T=DSM 18679T).

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).

Strain DCY37T was isolated from a soil sample of a ginseng field in the Republic of Korea and characterized in order to determine its taxonomic position. Cells were Gram-staining-positive, heterotrophic, strictly aerobic, non-motile short rods. 16S rRNA gene sequence analysis revealed that strain DCY37T belongs to the genus Microbacterium. According to 16S rRNA gene sequence analysis, it is closely related to Microbacterium aerolatum DSM 14217T (98.8 %), Microbacterium hydrocarbonoxydans DSM 16089T (98.5 %), Microbacterium natoriense JCM 12611T (98.5 %), Microbacterium foliorum (98.4 %) and Microbacterium phyllosphaerae (98.3 %). However, DNA–DNA hybridization studies showed reassociation values of less than 70 % between representative strains and DCY37T. The DNA G+C content was 64.5 mol%. Strain DCY37T possessed chemotaxonomic markers that were consistent with classification in the genus Microbacterium, i.e. MK-12 and MK-13 as the major menaquinones and anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as the predominant cellular fatty acids. The major cell wall sugars were ribose, xylose and galactose. The diamino acid in cell-wall hydrolysates of strain DCY37T was ornithine and major cell-wall amino acids were alanine, glycine, d-glutamic acid and serine. The major polar lipids were glycolipid, phosphatidylglycerol, diphosphatidylglycerol and unknown aminolipids. Based on these data, DCY37T (=KCTC 19526T =JCM 15516T) should be classified as the type strain of a novel species of the genus Microbacterium, for which the name Microbacterium ginsengiterrae sp. nov. is proposed.

A bacterial strain isolated from human faeces, M-165T, was characterized in terms of its phenotypic and biochemical features, cellular fatty acid profile, menaquinone profile and phylogenetic position (based on 16S rRNA gene sequence analysis). A 16S rRNA gene sequence analysis showed that the isolate was a member of the genus Parabacteroides. Strain M-165T was closely related to Parabacteroides merdae strains, showing 98 % sequence similarity. The strain was obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative, rod-shaped and was able to grow on media containing 20 % bile. Although the phenotypic characteristics of the strain M-165T were similar to those of P. merdae, the isolate could be differentiated from P. merdae by means of API 20A tests for l-arabinose and l-rhamnose fermentation. DNA–DNA hybridization experiments revealed the genomic distinctiveness of the novel strain with respect to P. merdae JCM 9497T (⩽60 % DNA–DNA relatedness). The DNA G+C content of the strain is 47.6 mol%. On the basis of these data, strain M-165T represents a novel species of the genus Parabacteroides, for which the name Parabacteroides johnsonii sp. nov. is proposed. The type strain is M-165T (=JCM 13406T=DSM 18315T).

A Gram-positive, yellow-pigmented, actinobacterial strain, DW152T, was isolated from a dairy industry effluent treatment plant. 16S rRNA gene sequence analysis indicated that strain DW152T exhibited low similarity with many species with validly published names belonging to the genera Micrococcus and Arthrobacter. However, phenotypic properties including chemotaxonomic markers affiliated strain DW152T to the genus Micrococcus. Strain DW152T had ai-C15 : 0 and i-C15 : 0 as major cellular fatty acids, and MK-8(H2) as the major menaquinone. The cell-wall peptidoglycan of strain DW152T had l-lysine as the diagnostic amino acid and the type was A4α. The DNA G+C content of strain DW152T was 68.0 mol%. In 16S rRNA gene sequence analysis, strain DW152T exhibited significant similarity with Micrococcus terreus NBRC 104258T, but the mean value of DNA–DNA relatedness between these strains was only 42.3 %. Moreover, strain DW152T differed in biochemical and chemotaxonomic characteristics from M. terreus and other species of the genus Micrococcus. Based on the above differences, we conclude that strain DW152T should be treated as a novel species of the genus Micrococcus, for which the name Micrococcus lactis sp. nov. is proposed. The type strain of Micrococcus lactis sp. nov. is DW152T ( = MTCC10523T  = DSM 23694T).

An anoxygenic, phototrophic gammaproteobacterium designated strain JA418T was isolated from a sediment sample collected from the Baitarani River, Orissa, India. The bacterium was a Gram-negative, motile rod with a single polar flagellum. Bacteriochlorophyll a and rhodopin were the major photosynthetic pigments. The organism grew best at slightly alkaline pH (8–8.5) and lacked chemotrophic growth. The major fatty acids were C16 : 0, C16 : 1 ω7c/C16 : 1 ω6c and C18 : 1 ω7c. A phylogenetic tree based on 16S rRNA gene sequence analysis showed that strain JA418T clusters with species of the genus Marichromatium belonging to the class Gammaproteobacteria. The highest 16S rRNA gene sequence similarities of strain JA418T were found with the type strains of Marichromatium gracile (95.9 %), Marichromatium indicum (95.6 %), Marichromatium purpuratum (95.5 %) and Marichromatium bheemlicum (95.6 %). The DNA base composition of strain JA418T was 71.4 mol% G+C (by HPLC). Based on the 16S rRNA gene sequence analysis and physiological and chemotaxonomic characteristics, strain JA418T is sufficiently different from other Marichromatium species to merit the description of a novel species, Marichromatium fluminis sp. nov., to accommodate it. The type strain is JA418T (=KCTC 5717T =NBRC 105221T).
