gen. nov., sp. nov., a new member of the from Tielu Harbour, Hainan, PR China Free

Abstract

A novel bacterial strain of the family ‘’ was isolated from mangrove of Tielu Harbour, Hainan, PR China. Strain S-15 was a Gram-stain-negative, short-rod-shaped, yellow-pigmented that could grow at 10–42 °C (optimum, 26–35 °C), at pH 5.0–9.0 (optimum, pH 5.5) and in 0.5–10.0 % w/v sea salt (optimum, 3.5–4.0 %). Cells of strain S-15 were 0.9–1.4 µm long, 0.8–0.9 µm wide, catalase-positive and oxidase-positive. Colonies on modified marine agar 2216 were 0.5–2.0 mm in diameter after incubation for 72 h at 28 °C. Analysis of 16S rRNA gene sequences revealed that strain S-15 was most closely related to ANORD5 (89.8 %). The major respiratory quinone of strain S-15 was menaquinone MK-7, and the dominant fatty acids were C iso, C iso G and C iso 3-OH. The major polar lipids were two unidentified aminolipids, phosphatidylethanolamine and six unidentified lipids. Analyses showed that the genome size was 3.52 Mb and the DNA G+C content was 35.6 mol%, which were higher than ANORD5 with 2.92 Mb genome size and 31.0 mol% G+C content, respectively. Based on morphological, physiological and phylogenetic data, strain S-15 is considered a type strain of a new species and a new genus of the family ‘’ for which the name gen. nov., sp. nov. is proposed. The type strain of is S-15 (=MCCC 1K03817=JCM 33804).
