Abstract

A Gram-stain-negative, aerobic, rod-shaped bacterium with peritrichous flagella, designated strain HB161719, was isolated from coastal sand collected from Tanmen Port in Hainan, PR China. The isolate was found to grow with 2–11 % (w/v) NaCl, at 15–45 °C and pH 6.0–10.0, with an optima of 2–3 % NaCl, 37 °C and pH 7.0, respectively. Chemotaxonomic analysis showed that Q-8 was detected as the sole respiratory quinone and that iso-C and summed features 3, 8 and 9 were the major cellular fatty acids. The G+C content of the genomic DNA was 58.2 mol%. Analysis of the 16S rRNA gene sequence of the strain showed an affiliation with the genus , sharing 98.7, 98.4, 97.8 and 97.8 % sequence similarities to the closest relatives of ABABA23, SPO729, CC-LN1-12 and GY2, respectively. Low DNA–DNA hybridization values showed that it formed a distinct genomic species. The combined phenotypic and molecular features supported that strain HB161719 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HB161719 (=CGMCC 1.13584=JCM 32688).
