Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 083058^T fell within the cluster comprising species of the genus Sphingomonas, clustering with Sphingomonas aestuarii K4^T, with which it shared highest 16S rRNA gene sequence similarity (99.2%). The chemotaxonomic properties of strain JSM 083058^T were consistent with those of the genus Sphingomonas. The predominant respiratory quinone was ubiquinone Q-10, and the major cellular fatty acids were summed feature 8 (C18:1ω7c/C18:1ω6c), C16:0, summed feature 3 (C16:1ω7c/C16:1ω6c) and C17:1ω6c. The polar lipids consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. The genomic DNA G+C content of strain JSM 083058^T was 65.5 mol%. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 083058^T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hunanensis sp. nov. is proposed.

The main polar lipids were phosphatidylethanolamine, an unidentified aminophospholipid, and two unidentified polar lipids. Phenotypic and chemotaxonomic data supported the affiliation of strain S7-2-11^T with the genus Spirosoma. The results of physiological and biochemical tests showed the genotypic and phenotypic differentiation of the isolate from recognized Spirosoma species. On the basis of its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain S7-2-11^T represents a novel species of the genus Spirosoma, for which the name Spirosoma pomorum sp. nov. is proposed. The type strain is S7-2-11^T (= KCTC 52726^T = JCM 32130^T).     

<Emphasis Type="Italic">Terrabacter ginsengisoli</Emphasis> sp. nov., isolated from ginseng cultivating soil

A Gram-positive, strictly aerobic, nonmotile, yellowish, coccus-rod-shaped bacterium (designated Gsoil 653^T) isolated from ginseng cultivating soil was characterized using a polyphasic approach to clarify its taxonomic position. The strain Gsoil 653^T exhibited optimal growth at pH 7.0 on R2A agar medium at 30°C. Phylogenetic analysis based on 16S rRNA gene sequence similarities, indicated that Gsoil 653^T belongs to the genus Terrabacter of the family Humibacillus, and was closely related to Terrabacter tumescens DSM 20308^T (98.9%), Terrabacter carboxydivorans PY2^T (98.9%), Terrabacter terrigena ON10^T (98.8%), Terrabacter terrae PPLB^T (98.6%), and Terrabacter lapilli LR-26^T (98.6%). The DNA G + C content was 70.5 mol%. The major quinone was MK-8(H₄). The primary polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidyl-ethanolamine. The predominant fatty acids were iso-C_15:0, iso-C_16:0, iso-C_14:0, and anteiso-C_15:0, as in the case of genus Terrabacter, thereby supporting the categorization of strain Gsoil 653^T. However, the DNA-DNA relatedness between Gsoil 653^T and closely related strains of Terrabacter species was low at less than 31%. Moreover, strain Gsoil 653^T could be both genotypically and phenotypically distinguished from the recognized species of the genus Terrabacter. This isolate, therefore, represents a novel species, for which the name Terrabacter ginsengisoli sp. nov. is proposed with the type strain Gsoil 653^T (= KACC 19444^T = LMG 30325^T).     

<Emphasis Type="Italic">Streptomyces serianimatus</Emphasis> sp. nov., isolated from a rhizophere soil

A novel actinomycete strain, designated YIM 45720^T, was isolated from a Cephalotaxus fortunei rhizophere soil sample collected from Yunnan Province, southwest China. The strain formed well-differentiated aerial and substrate mycelia. Chemotaxonomically, it contained LL-diaminopimelic acid in the cell wall. The cell-wall sugars contained ribose, mannose, and galactose with traces of glucose and xylose. Phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositol. MK-9 (H₈) was the predominant menaquinone. The major fatty acids (>10%) were iso-C_16:0, iso-C_15:1 and anteiso-C_15:0. The G + C content of the DNA was 70 mol%. Phylogenetic analysis data based on 16S rRNA gene sequence showed that strain YIM 45720^T formed a distinct branch with the type strain of Streptomyces scabrisporus JCM 11712^T within the genus Streptomyces. On the basis of the phenotypic and genotypic characteristics, strain YIM 45720^T (=DSM 41883^T = CCTCC AA 206006^T) is proposed as the type strain of a novel species, Streptomyces serianimatus sp. nov.     

<Emphasis Type="Italic">Lysobacter panacihumi</Emphasis> sp. nov., isolated from ginseng cultivated soil

A Gram-negative, non-motile, aerobic, catalase-, and oxidasepositive bacterial strain, designated DCY117^T, was isolated from ginseng cultivated soil in Gochang-gun, Republic of Korea, and was characterized taxonomically using a multifaceted approach. 16S rRNA gene sequence analysis revealed that strain DCY117^T showed highest similarity to Lysobacter ruishenii CTN-1^T (95.3%). Phylogenetic analysis revealed that closely related relatives of strain DCY117^T were L. aestuarii S2-C^T (95.1%), L. daejeonensis GH1-9^T (95.0%), and L. caeni BUT-8^T (94.9%). Diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), and phosphatidylethanolamine (PE) were the major polar lipids of strain DCY117^T. The major isoprenoid quinone was Q-8. The major cellular fatty acids of strain DCY117^T were iso-C_15:0, iso-C_16:0, and summed feature 9 (comprising iso-C_17:1ω9c and/or 10-methyl-C_16:0). Genomic DNA G + C content was 61.8 mol%. On the basis of our findings, strain DCY117^T is a novel species in the genus Lysobacter. We propose the name Lysobacter panacihumi sp. nov., and the type strain is DCY117^T (= KCTC 62019^T = JCM 32168^T).
