Abstract
A novel, Gram-stain-positive, moderately halophilic, endospore-forming, motile, facultatively anaerobic and rod-shaped strain, designated 0W14T, was isolated from a marine saltern of Wendeng, China. Optimal growth occurred at 37 °C, pH 7.5 and with 6.0 % (w/v) NaCl. MK-7 was the sole respiratory quinone and the peptidoglycan type of 0W14T was A4βl-Orn-d-Glu. The major cellular fatty acid (>10.0 %) in strain 0W14T was anteiso-C15 : 0. The polar lipid profile of strain 0W14T consisted of diphosphatidylglycerol, phosphatidylglycerol, two unknown glycolipids and four unknown phospholipids. The genomic DNA G+C content of the strain was 44.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 0W14T forms a phylogenetic lineage with members of the genus Lentibacillus within the family Bacillaceae. Based on data from the current polyphasic study, the isolate is proposed to represent a novel species of genus Lentibacillus, for which the name Lentibacillus sediminis sp. nov. is proposed. The type strain is 0W14T (=KCTC 33835T=MCCC 1H00171T).
