gen. nov., sp. nov., isolated from a marine solar saltern Free

Abstract

A novel Gram-stain-negative, facultatively anaerobic, flagellated and spiral-shaped bacterium, designated WDS2A16A was isolated from a marine solar saltern in Weihai, PR China. Growth was observed at 20–40 °C (optimal 33–37 °C), 1–15 % (w/v) NaCl (optimal 3–4 %) and pH 6.0–9.0 (optimal pH 7.5). Major cellular fatty acids (>10 %) were Cω and C. Phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid were detected as the predominant polar lipids. The sole respiratory quinone was Q-8. The DNA G+C content of strain WDS2A16A was 48.5 mol%. The 16S rRNA gene sequence similarities of WDS2A16A with other species were less than 91 %. The average nucleotide identity, DNA–DNA hybridization and amino acid identity of strain WDS2A16A with the most related strain YC6258 were 66.1, 19.3 and 48.1 %, respectively. Comparative analysis of 16S rRNA gene sequences and phenotypic characterization indicated that strain WDS2A16A represents a novel species in a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain is WDS2A16A (=KCTC 52225=MCCC 1H00139).
