A Gram-stain-neg., aerobic, gliding, reddish-orange-colored, rod-shaped strain, designated SR4T, was isolated from surface seawater sampled at Luhuitou fringing reef (South China Sea). Phylogenetic analyses based on the 16S rRNA gene, phylogenomic anal. of single-copy gene families and whole genome data affiliated it to the genus Flammeovirga. It was most closely related to Flammeovirga yaeyamensis NBRC 100898T (97.99% 16S rRNA gene similarity). The genome average nucleotide identity and DNA-DNA relatedness values between strain SR4T and its reference strains were less than 74.2 and 16.3%, resp. Growth occurred at 20-35° (optimum, 28°), pH 6.0-9.0 (optimum, pH 7.0) and in the presence of 1-6% (w/v) NaCl (optimum, 2-4%). The dominant fatty acids were C16 : 0, iso-C15 : 0 and C20 : 4 ω 6,9,12,15c. The polar lipid profile of strain SR4T comprised phosphatidylethanolamine, two glycolipids, two aminophospholipids and three unidentified lipids. The major respiratory quinone was MK-7. The DNA G + C content of strain SR4T was 34.20 mol%. On the basis of the polyphasic evidence, strain SR4T is proposed as representing a novel species of the genus Flammeovirga, for which the name Flammeovirga agarivorans sp. nov. is proposed. The type strain is SR4T (= KCTC 82075T = MCCC 1A17137T).
International Journal of Systematic and Evolutionary Microbiology published new progress about 16S rRNA Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 87-73-0 belongs to class alcohols-buliding-blocks, and the molecular formula is C6H10O8, Electric Literature of 87-73-0.
