Abstract |
A Gram-negative, non-motile, neutrophilic, rod-shaped, extremely halophilic archaeon, designated strain BG-1(T), was isolated from a salt lake, Lake Bagaejinnor, in Inner Mongolia, China. Strain BG-1(T) was able to grow at 25-55 degrees C, required at least 2.5 M NaCl for growth (with an optimum at 3.4 M NaCl) and grew at pH 6.0-9.0 (with an optimum at pH 7.5). Hypotonic treatment with less than 2.0 M NaCl caused cell lysis. Phylogenetic analysis of the almost-complete 16S rRNA gene sequence positioned the isolate within the genus Halorubrum in the family Halobacteriaceae. Strain BG-1(T) was most closely related to Halorubrum aidingense 31-hong(T) (98.8% sequence similarity), Halorubrum saccharovorum NCIMB 2081(T) (98.6%), Halorubrum lacusprofundi ACAM 34(T) (98.6%) and Halorubrum lipolyticum 9-3(T) (98.4%). However, values for DNA-DNA hybridization between strain BG-1(T) and the most closely related members of the genus Halorubrum were below 40%. Analysis of the polar lipids of strain BG-1(T) revealed the presence of mannosyl-2-sulfate-(1-4)-glycosyl-archaeol, the main glycolipid found in neutrophilic species of the genus Halorubrum. The G+C content of the genomic DNA was 69.4 mol% (T(m)). Comparison of the phenotypic characteristics of the strain with those of Halorubrum species supported the conclusion that BG-1(T) represents a novel species within this genus, for which the name Halorubrum kocurii sp. nov. is proposed. The type strain is BG-1(T) (=CECT 7322(T) =CGMCC 1.7018(T) =JCM 14978(T)).
