    Abstract:
    A halophilic archaeaon, strain LT12T, was isolated from saline soil sampled at the Tarim Basin, PR China. The novel strain stained Gram-negative, cells were rod-shaped, and formed light red-pigmented colonies on agar plate. Strain LT12T grew optimally at 3.1 M NaCl, 0.05 M MgCl2, 37 °C and pH 7.5. The cells lysed in distilled water and the minimal NaCl concentration to prevent cell lysis was 1.4 M. Based on the results of phylogenetic analyses of the 16S rRNA and rpoB' genes, strain LT12T was most closely related to Halostella salina CBA1114T(94.4-95.9  and 93.6 % similarities, respectively). The average nucleotide identity and in silico DNA-DNA hybridization values between strain LT12T and H. salina CBA1114T were 81.0 and 24.3 %, respectively. The major polar lipids of strain LT12T were phosphatidic acid, phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and three unidentified glycolipids. The DNA G+C content was 67.2 mol % (genome). Based on the phenotypic, chemotaxonomic and phylogenetic properties, strain LT12T represents a novel species of the genus Halostella for which the name Halostellalimicola sp. nov. is proposed. The type strain is LT12T (=CGMCC 1.14941T=JCM 30667T).
