A mesophilic, facultatively anaerobic, marine bacterium, designated strain FG1(T), was isolated from a seagrass bed sediment sample collected from Nanwan Bay, Kenting National Park, Taiwan. Cells grown in broth cultures were motile, Gram-negative rods; motility was normally achieved by two sheathed flagella at one pole of the cell. Strain FG1(T) required Na+ for growth, and exhibited optimal growth at 30-35 degrees C, pH 6-7 and about 4% NaCl. It grew anaerobically by fermenting glucose and other carbohydrates with production of various organic acids, including acetate, lactate, formate, malate, oxaloacetate, propionate, pyruvate and succinate, and the gases CO2 and H-2. The strain did not require either vitamins or other organic growth factors for growth. Its DNA G+C content was 45.9 mol%. It contained C12:0 as the most abundant cellular fatty acid. Characterization data, together with the results of a 16S rDNA-based phylogenetic analysis, indicate that strain FG1T represents a new species of the genus Vibrio. Thus, the name Vibrio aerogenes sp. nov. is proposed for this new bacterium. The type strain is FG1(T) (= ATCC 700797(T) = CCRC 17041(T)).
