英文摘要	A Gram-stain-negative, catalase- and oxidase-positive, aerobic, rod-shaped, motile strain (PYC7W(T)) was isolated from Lake Pengyanco on the Tibetan Plateau. Comparisons based on 16S rRNA gene sequences showed that strain PYC7W(T) belongs to the genus Halomonas, with Halomonas malpeensis YU-PRIM-29(T) and Halomonas johnsoniae T68687(T) as its closest neighbours (96.8 and 96.6% 16S rRNA gene sequence similarity, respectively), and only 93.1% 16S rRNA gene sequence similarity to Halomonas elongata ATCC 33173(T). The predominant respiratory quinone of strain PYC7W(T) is Q-9, with Q-8 as a minor component. The major fatty acids are C-18:1 omega 6c and / or C-18 omega 7c, C-16:0, C-16:1 omega 6c and/or C-16:1 omega 7c, and C-12:(0 )30H. The polar lipids of strain PYC7W(T) include phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and two unidentified phospholipids. Genome sequencing revealed a genome size of 4.79 Mbp and a G+C content of 62.9 mol%. DNA-DNA hybridization values of strain PYC7W(T) showed 45, 30 and 38% relatedness with Halomonas johnsoniae DSM 21197(T), Halomonas hamiltonii DSM 21196(T) and Halomonas stevensii DSM 21198(T), respectively. Combining phenotypic, biochemical, genotypic and DNA-DNA hybridization data, we propose that strain PYC7W(T) represents a novel species within the genus Halomonas and to have the name Halomonas montanilacus sp. nov.; PYC7W(T) (=CICC 24506(T) = KCTC 62529(T)) is the type strain.
