Halopelagius fulvigenes sp. nov., a halophilic archaeon isolated from a lake Liu, Bing-Bing and Tang, Shu-Kun and Cui, Heng-Lin and Zhang, Yong-Guang and Li, Li and Zhang, Yuan-Ming and Zhang, Li-Li and Li, Wen-Jun,, 63, 2192-2196 (2013), doi = https://doi.org/10.1099/ijs.0.045773-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Two extremely halophilic archaea, designated YIM 94188T and YIM 94189, were isolated from Qijiaojing lake in Xinjiang province, north-west China and subjected to taxonomic characterization using a polyphasic approach. The cells of the two strains were coccoid, non-motile and Gram-stain-negative. Colonies were pink–white-pigmented and aerobic. Growth occurred at 10–30 % (w/v) NaCl, 20–55 °C and pH 6.0–8.0 (optimum: 20–25 % NaCl, 37–42 °C, pH 6.5–7.0). Magnesium was necessary for growth in the range of 0.2–1.2 M. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains belonged to the genus Halopelagius showing 98.5 % sequence similarity to the closest phylogenetic neighbour, Halopelagius inordinatus RO5-2T. In addition, the DNA–DNA hybridization values of strains YIM 94188T and YIM 94189 to Halopelagius inordinatus RO5-2T were 35.7 % and 37.7 %, respectively. Polar lipid analyses revealed that the two strains contained phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP-Me), sulfated mannosyl glucosyl diether (S-DGD-1) and mannosyl glucosyl diether (DGD-1). The DNA G+C contents of strains YIM 94188T and YIM 94189 were 66.3 mol% and 64.6 mol%, respectively. On the basis of physiological and chemotaxonomic data, and phylogenetic analysis, strains YIM 94188T and YIM 94189 were classified as representing a novel species in the genus Halopelagius . The name Halopelagius fulvigenes sp. nov. is proposed, with YIM 94188T ( = CCTCC AB 2010456T = JCM 17506T) as the type strain., language=, type=
