Abstract:
A novel bacterium, designated strain F028-2 T , was isolated from seawater at Damupo beach in Pohang, Korea, and investigated in a taxonomic study using a polyphasic approach. This novel strain was strictly aerobic, non-motile, Gram-stain-negative and rod-shaped, and occasionally formed aggregates. The temperature, pH and NaCl ranges for growth were 4–30 °C, pH 6.5–9.0 and 1–7 % (w/v), respectively. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain F028-2 T formed a lineage within the family Rhodobacteraceae of the class Alphaproteobacteria , and was closely related to members of the genera Sagittula and Antarctobacter with 96.3–96.4 % sequence similarities. The polar lipid profile of strain F028-2 T comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids, one unidentified phospholipid and six unidentified lipids. The predominant cellular fatty acids were C 18 : 1 ω7 c and C 12 : 1 3-OH. The genomic DNA G+C content of strain F028-2 T was 61.6 mol% and the major respiratory quinone was Q-10. Based on phenotypic, phylogenetic and genotypic data, strain F028-2 T is considered to represent a novel species in the genus Sagittula , for which the name Sagittula marina sp. nov. is proposed. The type strain is F028-2 T ( = KCTC 23543 T = JCM 17627 T ). An emended description of the genus Sagittula is also proposed.
