Tianweitania sediminis gen. Nov., sp. nov., a member of the family Phyllobacteriaceae, isolated from subsurface sediment core

A bacterial strain, designated Z8^T, was isolated from the terrestrial sediment of the Mohe Basin in north-east China. Phylogenetic analyses of 16S rRNA genes showed that this strain belonged to the family Phyllobacteriaceae, and was most closely related to Phyllobacterium bourgognense, with a sequence similarity of 96.9 %. The major cellular fatty acids were summed feature 4 (iso-C_17:1 I and/or anteiso-C_{17: 1} B) and summed feature 8 (C_{18: 1}ω7c and/or C_{18: 1} ω6c. The major respiratory quinone was ubiquinone-10. The three major polar lipids of strain Z8^T consisted of glycolipids, phosphatidylethanolamine and phosphatidylmethylethanolamine. The DNA G + C content was 59.6 mol%. The chemotaxonomic characteristics of strain Z8^T differed in some respects from those of members of the family Phyllobacteriaceae. Based on phylogenetic, phenotypic and chemotaxonomic data, strain Z8^T is considered to represent a novel species of a novel genus within the family Phyllobacteriaceae, for which the name Tianweitania sediminis gen. nov., sp. nov. is proposed. The type strain is Z8^T (=CGMCC 1.12944^T=JCM 30358^T).
