Abstract

An aerobic, Gram-staining-negative, rod or ovoid-shaped bacterial isolate, strain NH52J, was isolated from a sandy sediment sample from the South China Sea. Strain NH52J exhibited tumbling motility, formed beige or faint pink colonies, gave a positive reaction in tests for catalase and oxidase and required NaCl for growth. Optimal growth was observed at pH 7.8–9.3, at 30 °C and in the presence of 2.0–4.0 % (w/v) NaCl. The novel strain did not synthesize bacteriochlorophyll , and the DNA G+C content was 62 %. The major fatty acids were C 7, C and C 7 11-methyl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NH52J was affiliated to the genus of the class . and were the most closely related recognized species to strain NH52J with 16S rRNA gene sequence similarity values of 95.0 and 95.7 %, respectively. Sequence similarity values between strain NH52J and other phylogenetically related species were all below 95.0 %. Based on the phenotypic, chemotaxonomic and phylogenetic data presented, strain NH52J is considered to represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is NH52J (=LMG 24840=CCTCC AB 208317=MCCC 1A03543).
