A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

Abstract A novel bacterium of the Streptomyces genus, designated TRM S81-3T, was isolated from soil in cotton fields of Xinjiang, China. Comparative 16S rRNA gene sequence analysis indicated that strain TRM S81-3T ismost closely related to Streptomyces naganishii NBRC 12892T (98.96% sequence similarity); however, the average nucleotide identity (ANI) between strains TRM S81-3T and S. naganishii NBRC 12892T is relatively low (86.26%). Strain TRM S81-3T possesses LL-diaminopimelic acid as the diagnostic cell-wall diamino acid, MK-9(H4), MK-9(H6), and MK-9(H10) as the major menaquinones, and polar lipids including DPG, PE, PC, PI, PME, NPG and PL. The major fatty acids are iso-C16:0, anteiso-C15:0, anteiso-C17:1 ω9c, anteiso-C17:0, iso-C15:0, and C14:0. The genomic DNA G+C content is 72.1%. Based on the evidence from this polyphasic study, strain TRM S81-3T represents a novel species of Streptomyces, for which the name Streptomyces grisecoloratus is proposed. The type strain is TRM S81-3T (=CCTCC AA 2020002T=LMG 31942T).

A Gram-negative-staining, motile, rod-shaped, aerobic bacterial strain, designated MJ02T, was isolated from sludge of a leachate treatment plant in Daejeon (South Korea) and was characterized to determine its taxonomic position by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ02T belonged to the family Rhizobiaceae, class Alphaproteobacteria, and was most closely related to Shinella yambaruensis MS4T (97.6 % sequence similarity) and Shinella fusca DC-196T (97.5 %). The G+C content of the genomic DNA of strain MJ02T was 64.3 mol%. The detection of a quinone system with ubiquinone Q-10 as the predominant respiratory lipoquinone and a fatty acid profile with C18 : 1ω7c (45.8 %) and C16 : 0 (21.8 %) as the major components supported the affiliation of strain MJ02T to the genus Shinella. However, strain MJ02T exhibited relatively low levels of DNA–DNA relatedness with respect to S. fusca DSM 21319T (17±7 %) and S. yambaruensis KACC 14483T (12±6 %), showing clearly that the isolate constituted a new genospecies. Strain MJ02T could be clearly differentiated from its phylogenetic neighbours on the basis of several phenotypic, genotypic and chemotaxonomic features. Therefore, strain MJ02T is considered to represent a novel species of the genus Shinella, for which the name Shinella daejeonensis sp. nov. is proposed. The type strain is MJ02T ( = KCTC 22450T = JCM 16236T).

Identification of a bacterial strain, designated CJ71T, was carried out using a polyphasic taxonomic approach. Strain CJ71T was isolated from sediment from the estuarine wetland of the Han River, South Korea, by enrichment culture using pyrene as the sole carbon and energy source. The isolate was white-pigmented, rod-shaped, Gram-positive, strictly aerobic and motile. 16S rRNA gene sequence analysis revealed that strain CJ71T had the highest sequence similarity (96.9 %) to Brevibacillus formosus DSM 9885T. The predominant cellular fatty acids in strain CJ71T were anteiso-C15 : 0 (49.5 %), iso-C15 : 0 (16.9 %), iso-C14 : 0 (16.9 %) and iso-C16 : 0 (4.9 %). The major isoprenoid quinone was MK-7. The G+C content of the genomic DNA was 52.4 mol%. Results from the polyphasic taxonomic study suggest that strain CJ71T represents a novel species of the genus Brevibacillus for which the name Brevibacillus fluminis sp. nov. is proposed; the type strain is CJ71T (=KACC 13381T=JCM 15716T)
