Abstract
- A novel bacterium of the genus Pontibacter, designated GY10130<superscript>T</superscript>, was isolated from rhizosphere soil of a mangrove plant Rhizophora stylosa collected from Guangxi province, China. Strain GY10130<superscript>T</superscript> was Gram-stain negative, positive for oxidase activities, aerobic, short rod-shaped cells without flagella. Growth was observed at 10–40 °C (optimum, 28 °C), pH 6.0–9.0 (optimum, 7.0) and NaCl concentrations of 0–4% (optimum, 1%). Strain GY10130<superscript>T</superscript> is closely related to members of the genus Pontibacter, namely P. beigongshangensis CGMCC 1.17104<superscript>T</superscript> (97.8%) and P. amylolyticus CGMCC 1.12749<superscript>T</superscript> (95.0%), P. humi SWU8<superscript>T</superscript> (94.7%), and less than 94.0% with other currently described type strains of Pontibacter. The strain GY10130<superscript>T</superscript> showed an ANI value of 80.6% and dDDH value of 23.2% with P. beigongshangensis CGMCC 1.17104<superscript>T</superscript>, followed by P. amylolyticus CGMCC 1.12749<superscript>T</superscript> with ANI and dDDH values of 72.9 and 13.8%, respectively. Strain GY10130<superscript>T</superscript> contains carotenoid-like pigments, but flexirubin-type pigments were absent. The cellular fatty acids (> 10%) consist of summed feature 4 (17:1 iso I/anteiso B) and iso-C<subscript>15:0</subscript>. The predominant menaquinone is MK-7. The polar lipids comprise phosphatidylethanolamine, two unidentified glycolipids, two unidentified aminolipids and six unidentified phospholipids. The genome length of strain GY10130<superscript>T</superscript> was 6.2 Mbp with a DNA G + C content of 47.1 mol% and 4727 protein-coding genes. The result of polyphasic taxonomic study show strain GY10130<superscript>T</superscript> represents one novel species of Pontibacter, Pontibacter qinzhouensis sp. nov., with the type strain GY10130<superscript>T</superscript> (=NBRC 113901<superscript>T</superscript> = CGMCC 1.16772<superscript>T</superscript>).
