Here, we describe a novel bacterial strain, designated T37^T, which was isolated from the marine sediment of Xiaoshi Island, PR China. Growth of strain T37^T occurs at 15–40 °C (optimum 37 °C), pH 6.0–9.0 (optimum 7.5), and in the presence of 0.5–5.5% (w/v) NaCl (optimum 1.5%). Characteristic biochemical traits of the novel strain include MK-9 as the major menaquinone. The major fatty acids identified were iso-C_14:0 and C_16:1ω9c (oleic acid). Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and phosphoglycolipids were the major cellular polar lipids. The G + C content of genomic DNA was 58.4 mol%. Unusual outer membrane features deduced from the analysis of cell morphology point towards the formation of an enlarged periplasmic space putatively used for the digestion of macromolecules. Phylogenetic analyses based on 16S rRNA genes and the genome indicated that strain …
