Oceanobacillus aidingensis sp. nov., a moderately halophilic bacterium.

ABSTRACT: Two Gram-positive, rod-shaped moderately halophilic bacterial strains, designated AD7-25(T) and AB-11, were isolated from Aiding and Manasi salt lakes in Xinjiang of China, respectively. The strains were found to be able to grow at NaCl concentrations of 0-21 % (w/v), with optimum growth occurring at 6-8 % (w/v) NaCl. The optimal temperature and pH for growth were determined to be 33-37 °C and pH 7.0-7.5. Cells of the strains are motile by means of polar flagella. Both strains can produce ellipsoidal spores. The major cellular fatty acids were identified as anteiso-C15:0, iso-C15:0, iso-C14:0, anteiso-C17:0 and iso-C16:0. The diamino acid in the peptidoglycan and the major quinone system were determined to be meso-diaminopimelic acid (meso-DAP) and MK-7, respectively. The DNA G+C contents
