| Abstract |
Strain HB172011T 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 Amaricoccus and has 95.6-96.3% 16S rRNA gene sequence similarities to the four Amaricoccus 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 (C18:1ω7c and/or C18:1ω6c), C16:0, C19:0 cyclo ω8c and summed feature 2 (C16:1 iso I and/or C14:0-3 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 HB172011T represents a novel species of Amaricoccus, for which the name Amaricoccus solimangrovi sp. nov. is proposed. The type strain is HB172011T (=CGMCC 1.16728T=JCM 33334T).
