Abstract

Strain HB172011 was isolated from mangrove soil sampled at the Bamenbay mangrove forest, PR China. Cells were easily recognized under the microscope as cocci that were usually arranged in distinctive tetrads. Results of phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate belongs to the genus and has 95.6–96.3% 16S rRNA gene sequence similarities to the four type strains. The strain was aerobic or facultatively anaerobic, Gram-stain-negative and non-motile. Cells were found to grow at 10–40 °C (optimum, 30 °C), pH 6.0–9.0 (optimum, pH 7.0) and with 0–9.0% (w/v) NaCl (optimum, 2–4%). Major fatty acids were feature 8 (C 7 and/or C 6), C, C cyclo 8 and summed feature 2 (C iso I and/or C–3 OH). Genome sequencing revealed a genome size of 4.87 Mbp and a DNA G+C content of 69.9 mol %. Based on these data, strain HB172011 represents a novel species of , for which the name sp. nov. is proposed. The type strain is HB172011 (=CGMCC 1.16728=JCM 33334).
