A Gram-negative, extremely halophilic, coccoid archaeal strain, CM5 T , was isolated from a crude sea-salt sample collected near Qingdao, China. The organism grew optimally at 35–40 °C and pH 6.0 in the presence of 20 % (w/v) NaCl. Its colonies were red colour it could use glucose as sole carbon source for growth. 16S rRNA gene sequence most closely related to those Halococcus species. pattern antibiotic susceptibility similar other described Biochemical tests revealed no sign H 2 S production or gelatin liquefaction. main polar lipids strain phosphatidylglycerol, phosphatidylglycerol methylphosphate sulfated diglycosyl diether. No sulfate present. DNA G+C content 61.2 mol% gave DNA–DNA reassociation values 33.7, 57.1 29.6 %, respectively, with salifodinae DSM 8989 dombrowskii 14522 morrhuae ATCC 17082 . Based on its morphological chemotaxonomic properties phylogenetic analysis data, we propose that should be classified within novel species, qingdaonensis sp. nov., (=CGMCC 1.4243 =JCM 13587 ) type strain.
