Jonesia luteola sp. nov., a bacterium isolated from Xinjiang Province, China

Abstract

A Gram-positive, facultative anaerobe microorganism, designated YIM 93067T, was isolated from a salt lake in Xinjiang Province of China and subjected to a polyphasic taxonomic study. Strain YIM 93067T grew at 5–40 °C, 0–8.0 % (w/v) NaCl and pH 7.0–9.0. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the organism belongs to the genus Jonesia and exhibited a sequence similarity of 98.8 % to the closely related type strain Jonesia quinghaiensis DSM 15701T. The predominant menaquinone was MK-9 and the major fatty acids were anteiso-C15:0 and C16:0. The polar lipids consisted of diphosphatidylglycerol, glycolipid, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and one unidentified phospholipid. The G+C content of the genomic DNA was 57.4 mol%. Based on the results of phylogenetic, physiological and chemotaxonomic comparative analyses, the isolate is assigned to a novel species of the genus Jonesia, for which the name Jonesia luteola sp. nov. is proposed, with the type strain YIM 93067T (=DSM 21367T = CCTCC AB 2014350T).
