sp. nov., isolated from the seawater of Dongshan Island.

A taxonomic study was carried out on strain yzlin-01, isolated from Dongshan Island seawater. The bacterium was Gram-stain-negative, catalase-positive, oxidase-negative, rod-shaped, and motile by polar flagella. Growth was observed at temperatures of 10-40 °C, at salinities of 0.5-18 %, and at pH of 6-10. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain yzlin-01 belonged to the genus , with the highest sequence similarity to YU-PRIM-29 (96.7 %), followed by T68687 (96.4 %) and M12 (96.4 %), and other species of the genus (93.4-96.3 %). The ANI and digital DNA-DNA hybridization estimate values between strain yzlin-01 and the closest type strain YU-PRIM-29 were 77.44 and 21.6 %, respectively. The principal fatty acids were summed feature 8 (consisting of C c and/or C c; 55.7 %), C (20.6 %), C 3-OH (6.8 %), summed feature 3 (consisting of C c and/or C c; 5.1 %). The G+C content of the chromosomal DNA was 60.0 mol %. The respiratory quinone was identified as Q-9 (100 %). Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, aminophospholipid, and three unidentified phospholipids were present. Combined genotypic and phenotypic data suggest that strain yzlin-01 represents a novel species within the genus , for which the name sp. nov. is proposed, with the type strain yzlin-01 (=GDMCC 1.3202=KCTC 92467).
