| Abstract |
A translucent, white, Gram-reaction-negative, facultatively anaerobic, non-flagellated, slightly curved or curved bacterial strain, designated YT8(T), was isolated from the fresh water of the Maotai section of Chishui River, China. Cells were catalase-positive and oxidase-positive. Phylogenetic analyses of 16S rRNA gene sequences revealed that strain YT8(T) is a member of the genus Arenimonas with similarity to other members of this genus ranging from 93.7 to 95.0 %. The major isoprenoid quinone was ubiquinone 8 (Q-8), major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, two unidentified phospholipids and two unidentified polar lipids, while major fatty acids were iso-C15 : 0, iso-C14 : 0 and anteiso-C15 : 0. The DNA G+C content of strain YT8(T) was 66.6 mol%. On the basis of phenotypic, phylogenetic and genotypic features studied, strain YT8(T) is suggested to represent a novel species of the genus Arenimonas, for which the name Arenimonas maotaiensis sp. nov. is proposed. The type strain is YT8(T) ( = CGMCC 1.12726(T) = JCM 19710(T)).
