- Abstract
A Gram-positive bacterium, designated SCSIO 15042, was isolated from a sediment of the South China Sea and was subjected to a polyphasic taxonomic study. The isolate grew at 20-60 °C, pH 6.0-10.0 and it could grow with up to 10 % (w/v) NaCl. The cell-wall diamino acid was found to be meso-diaminopimelic acid. Polar lipids were found to be diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine and an unknown polar lipid. The only menaquinone was determined to be MK-7. The major fatty acids were identified as C ω7 c/C ω6 c, C, iso-C, anteiso-C, and iso-C. The DNA G+C content of strain SCSIO 15042 was determined to be 43.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences affiliated strain SCSIO 15042 to the genus Bacillus. Levels of 16S rRNA gene sequence similarities between strain SCSIO 15042 and Bacillus herbersteinensis D-1-5a, Bacillus infantis SMC 4352-1, Bacillus novalis LMG 21837 and Bacillus drentensis LMG 21831 were 96.2, 96.2, 96.1 and 96.1 %, respectively. Based on the evidence of the present polyphasic study, strain SCSIO 15042 is considered to represent a novel species of the genus Bacillus, for which the name Bacillus abyssalis sp. nov. is proposed. The type strain is SCSIO 15042 (=DSM 25875 = CCTCC AB 2012074 = NBRC 109102).
