| Abstract |
A novel Gram-stain-positive, motile and facultatively anaerobic strain, designated NC2-31T, was isolated from sediment from the coast of Weihai, PR China. Optimal growth occurred at 37 °C, pH 7.5 and with 2.0-3.0 % (w/v) NaCl. MK-7 was the major respiratory quinone. Meso-diaminopimelic acid was a diagnostic diamino acid in the peptidoglycan. The major polar lipids of NC2-31T were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). The genomic DNA G+C content of the strain was 46.3 mol%. The predominant cellular fatty acids (>10.0 %) of NC2-31T were iso-C15 : 0 (18.9 %), anteiso-C15 : 0 (15.8 %), summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) (15.3 %) and iso-C16 : 0 (10.3 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that NC2-31T should be classified as representing a member of the genus Bacillus. Based on data from the current polyphasic study, NC2-31T represents a novel species within the genus Bacillus, for which the name Bacillusmarinisedimentorum sp. nov. is proposed with type strain NC2-31T (=KCTC 33721T=MCCC 1K01239T).
