ABSTRACT
During a study of the bacterial diversity of mangrove habitats, a novel Gram-stain-negative, rod-shaped bacterium designated as SAOS 153DT was isolated. Sequence alignment and molecular phylogenetic analyses based on 16S rRNA and core gene sequence of strain SAOS 153DT with closely related taxa revealed a sequence identity of 99.4â% and clustering with Yangia pacifica DX5-10T. The fatty acids summed feature 8 (C181 ω7c/C181 ω6c) and the lipids phosphatidylglycerol, phosphatidylethanolamine and an unknown phospholipid were the major components of the cell wall. The only ubiquinone type present was Q-10. The genomic DNA G+C content of the strain calculated from whole genome sequencing was 66.9 mol%. These chemotaxonomic and genomic characteristics supported the molecular phylogenetic analysis and placed the strain well within the radiation of the genus Yangia. The overall genome related indices using digital DNA-DNA hybridization (35.4â%) and ortho-average nucleotide identity (88.1â%) values were much lower than the recommended thresholds for species delineation, which further consolidated the novel species status of strain SAOS 153DT within the genus Yangia as Yangia mangrovi sp. nov. The type strain is SAOS 153DT (=JCM 31345T=KCTC 52280T=MTCC 12749T).
