Abstract

A Gram-stain-negative, rod-shaped, exopolysaccharide-producing, strictly aerobic bacterium with a single polar flagellum, designated strain HL22-2, was isolated from a phosphate mine situated in a suburb of Kunmming in Yunnan province in south-western China. The taxonomic status of this strain was evaluated by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain HL22-2 was related to members of the genus . 16S rRNA gene sequence similarities between strain HL22-2 and KMM 1447, AL15-21 and ATCC 17588 were 98.9, 98.10 % and 98.06 %, respectively. The major cellular fatty acids were Cω7, C and summed feature 3 (Cω7 and/or Cω6). The DNA G+C content was 60.3 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness values, strain HL22-2 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HL22-2 ( = CGMCC 1.12273 = DSM 25974).
