A coccoid and amorphous-shaped, non-gliding, proteorhodopsin-containing, yellow bacterium, designated strain SG-18(T), was isolated from seawater in the western North Pacific Ocean near Japan. The strain was Gram-stain-negative, obligately aerobic, heterotrophic and oxidase-positive. It hydrolysed aesculin but not DNA, urea, gelatin or agar. Growth occurred in the presence of 1-5â% NaCl, with optimum growth at 2â% NaCl. The strain grew at 15-37 °C with an optimum temperature of 25-30 °C. The DNA G+C content of the genomic DNA of strain SG-18(T) was 47.0 mol% (HPLC). The predominant isoprenoid quinone was MK-6, and major cellular fatty acids were iso-C15â:â1 G, iso-C15â:â0, iso-C15â:â0 3-OH. Phylogenetic trees generated by using 16S rRNA gene sequences revealed that strain SG-18(T) belonged to the family Flavobacteriaceae and showed 92.7â% sequence similarity to the most closely related species, Croceitalea eckloniae DOKDO 025(T). On the basis of phenotypic and phylogenetic features, strain SG-18(T) is classified as representing a novel species of a new genus within the family Flavobacteriaceae, for which the name Aureicoccus marinus gen. nov., sp. nov. is proposed. The type strain of the type species is SG-18(T) (â=âNBRC 108814(T)â=âKCTC 23967(T)).
