A Gram-stain-negative, aerobic, yellow-pigmented, rod-shaped bacterium, designated strain SC_3T, was isolated from pesticide-contaminated soil sediment. The strain was able to mineralize 2-phenoxybenzoic acid. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SC_3T formed a monophyletic lineage in the genus Sphingobium, and showed highest similarity to the type strains of Sphingobium abikonense (97.0 %), followed by Sphingobium lactosutens (96.8 %) and Sphingobium cloacae (96.7 %). The DNA–DNA relatedness between strain SC_3T and its closest phylogenetic neighbours was lower than 70 %. The major fatty acids (>5 % of the total) were summed feature 8 (comprising C18:1ω7c/C18:1ω6c), summed feature 3 (comprising C16:1ω7c/C16:1ω6c), C14:0 2-OH, C16:0 and C17:1ω6c. The predominant quinone was ubiquinone Q-10, and the major polyamine was spermidine. The polar lipid profile contained diphosphatidylglycerol (DPG), sphingoglycolipid (SGL), phosphatidylethanolamine (PDME), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), phosphatidylmonomethylethanolamine (PMME), an unknown aminolipid (AL), two unknown lipids (L1, L2) and several unknown phospholipids (PL1–6). The genomic DNA G+C content of strain SC_3T was 62.9 mol%. On the basis of phenotypic, chemotaxonomic, phylogenetic and genotypic data, strain SC_3T represents a novel species of the genus Sphingobium, for which the name Sphingobium phenoxybenzoativorans sp. nov. is proposed. The type strain is SC_3T ( = CCTCC AB 2014349T = KACC 42448T).

A New Species

A pink-red pigmented, non-motile, coccoid bacterial strain, ST0316T, was isolated from dust samples collected from the stratosphere in Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that it belonged to the genus Deinococcus. DNA G+C content (69.8 mol%), desiccation tolerance, and resistance to gamma-rays [D10 (dose required to reduce the bacterial population by 10-fold) >8 kGy] and UV radiation (D10 1000 J m−2) supported the affiliation of strain ST0316T to the genus Deinococcus. The major peptidoglycan amino acids were d-glutamic acid, glycine, d-alanine, l-alanine and ornithine. Predominant fatty acids were C16 : 1 ω7c, C16 : 0, C17 : 0 and iso-C17 : 0. Strain ST0316T diverged from recognized species of the genus Deinococcus, showing less than 93.0 % similarity values to its closest relatives Deinococcus apachensis, D. aerius, D. geothermalis and D. murrayi. Strain ST0316T also differed from the type strains of closely related species in its polar lipid profile, nitrate reduction and carbon-source assimilation tests. Therefore, we propose a new species of the genus Deinococcus, Deinococcus aetherius sp. nov. (type strain, ST0316T =JCM 11751T =DSM 21230T).

A Gram-negative, motile, rod-shaped bacterium (WSF2T) was isolated from coastal seawater of the Boso Peninsula in Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain WSF2T represented a separate lineage within the genus Pseudovibrio. The DNA G+C content of strain WSF2T was 51.7 mol%. DNA–DNA hybridization values between strain WSF2T and the type strains of Pseudovibrio species were significantly lower than those accepted as the phylogenetic definition of a species. Furthermore, some biochemical characteristics indicated that strain WSF2T differed from other Pseudovibrio species. Based on these characteristics, it is proposed that the isolate represents a novel species, Pseudovibrio japonicus sp. nov. The type strain is WSF2T (=IAM 15442T=NCIMB 14279T=KCTC 12861T).

A novel actinomycete, designated strain 06182M-1T, was isolated from a mangrove soil sample collected from Chiayi County in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.8 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain 06182M-1T within the genus Isoptericola. However, the low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain 06182M-1T represents a novel species of the genus Isoptericola, for which the name Isoptericola chiayiensis sp. nov. is proposed. The type strain is 06182M-1T ( = BCRC 16888T  = KCTC 19740T).
