摘要:	A Gram-stain-negative, rod-shaped, exopolysaccharide-producing, strictly aerobic bacterium with a single polar flagellum, designated strain HL22-2(T), 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(T) was related to members of the genus Pseudomonas. 16S rRNA gene sequence similarities between strain HL22-2(T) and Pseudomonas xanthomarina KMM 1447(T), Pseudomonas alcaliphila AL15-21(T) and Pseudomonas stutzeri ATCC 17588(T) were 98.9, 98.10% and 98.06%, respectively. The major cellular fatty acids were C(18 : 1)omega7c, C(16 : 0) and summed feature 3 (C(16 : 1)omega7c and/or C(16 : 1)omega6c). 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(T) represents a novel species of the genus Pseudomonas, for which the name Pseudomonas kunmingensis sp. nov. is proposed. The type strain is HL22-2(T) ( = CGMCC 1.12273(T) = DSM 25974(T)).
