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

A bacterial strain, designated Z8T, 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-C17 : 1 I and/or anteiso-C17 : 1 B) and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The major respiratory quinone was ubiquinone-10. The three major polar lipids of strain Z8T consisted of glycolipids, phosphatidylethanolamine and phosphatidylmethylethanolamine. The DNA G+C content was 59.6 mol%. The chemotaxonomic characteristics of strain Z8T differed in some respects from those of members of the family Phyllobacteriaceae. Based on phylogenetic, phenotypic and chemotaxonomic data, strain Z8T 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 Z8T ( = CGMCC 1.12944T = JCM 30358T).
