“…Sulfated mannosylglucosylglycerol diether was detected among the lipids of strain H4 T , as well as two unknown glycolipids. The overall phospholipid pattern of strain H4 T was characteristic of members of the genus Halococcus (Ross et al, 1985 ;Wainø et al, 2000). Strain H4 T produced carotenoid pigments characteristic of members of the haloarchaea, as determined with methanol\acetone extracts.…”

“…The extremely halophilic, aerobic members of the Archaea are classified within the family Halobacteriaceae, order Halobacteriales, with 20 currently recognized genera: Halalkalicoccus (Xue et al, 2005), Haloarcula (Torreblanca et al, 1986), Halobacterium (Grant, 2001a), Halobaculum (Oren et al, 1995), Halobiforma (Hezayen et al, 2002), Halococcus (Grant, 2001b), Haloferax (Torreblanca et al, 1986), Halogeometricum (Montalvo-Rodríguez et al, 1998), Halomicrobium (Oren et al, 2002), Halorhabdus (Wainø et al, 2000), Halorubrum (McGenity & Grant, 1995), Halosimplex (Vreeland et al, 2002), Haloterrigena (Ventosa et al, 1999), Natrialba (Kamekura & Dyall-Smith, 1995), Natrinema (McGenity et al, 1998), Natronobacterium (Tindall et al, 1984), Natronococcus (Tindall et al, 1984), Natronolimnobius (Itoh et al, 2005), Natronomonas (Kamekura et al, 1997) and Natronorubrum (Xu et al, 1999). The current taxonomic classification of this archaeal group is based largely on 16S rRNA gene sequence comparison and chemotaxonomic criteria, particularly polar lipid composition ).…”

Halovivax asiaticus gen. nov., sp. nov., a novel extremely halophilic archaeon isolated from Inner Mongolia, China Strain EJ-46 T , a novel pleomorphic, aerobic, extremely halophilic member of the Archaea was isolated from sediment of the saline Lake Ejinor, in Inner Mongolia, China. This organism was neutrophilic and required at least 15 % (2?5 M) NaCl for growth. MgCl 2 was not required. The isolate was able to grow at pH 6?0-9?0. Optimum growth occurred in media containing 20 % (3?4 M) NaCl at pH 7?0-7?5. Polar lipid analysis revealed the presence of phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester, derived from both C 20 C 20 and C 20 C 25 glycerol diethers. Four glycolipids were detected, one of which may be novel. The DNA G+C content was 60?3 mol%. 16S rRNA gene analysis revealed that strain EJ-46 T was a member of the phylogenetic group defined by the family Halobacteriaceae, and the highest 16S rRNA gene similarity values of 94?9 and 94?8 % were obtained with the haloalkaliphilic species of the genus Natronococcus, Natronococcus occultus and Natronococcus amylolyticus, respectively. Based on the phenotypic, genotypic and phylogenetic analyses, it is proposed that the novel isolate should be classified as representing a new genus and species, for which the name Halovivax asiaticus gen. nov., sp. nov. is proposed. The type strain is EJ-46 T (=CGMCC 1.4248 T =CECT 7098 T ).The extremely halophilic, aerobic members of the Archaea are classified within the family Halobacteriaceae, order Halobacteriales, with 20 currently recognized genera: Halalkalicoccus Members of the Halobacteriaceae are usually pink-to redpigmented because of the presence of carotenoids (Kamekura & Dyall-Smith, 1995;Hezayen et al., 2001;Grant et al., 2001). They have been isolated from various hypersaline environments, such as saline lakes (e.g. Franzmann et al., 1994;Norton et al., 1993). The haloarchaea are the most halophilic organisms known and are dominant in hypersaline environments in which the salt concentration exceeds 25 % (w/v) (Rodriguez-Valera et al., 1981). They often appear at such high density that they impart a typical red colour to the hypersaline brines.Hypersaline environments are commonly found in China. In addition to many coastal salterns, a number of salt lakes, soda lakes and salt-rich deserts are located in various geographical areas of China, e.g. Xinjiang, Inner Mongolia and Tibet Autonomous Regions. A number of new members of the Halobacteriaceae have been isolated from these saline environments (Xu et al., 1999(Xu et al., , 2001Xin et al., 2000Xin et al., , 2001Fan et al., 2004;Feng et al., 2004Feng et al., , 2005. In this paper, we report the isolation of strain EJ-46 T from Lake Ejinor in Inner Mongolia, China. The complete 16S rRNA gene sequence of strain EJ-46 T as well as the polar lipid composition were analysed and the phenotypic characteristics were compared with those of other extremely halophilic archaea to determine the taxonomic position of strain EJ-46 T . On the basis of t...
