Cells are Gramstainnegative, flagellated and rod shaped. Colonies are circular, convex, entire and beige colored on TSA medium supplemented with 0.5% yeast extract after 48 h incubation at 25℃. Cells reduce nitrate to nitrite and are positive for urease, alkaline phosphatase, leucine arylamidase, acid phosphatase, naphtholASBIphosphohydrolase (API 20NE/ZYM). Assimilate acetate, lactate, glycogen (API ID 32GN) and utilize Dfructose, pectin, galactonic lactone, Dgluconic acid, Dglucuronic acid, glucuronamide, mucic acid, methyl pyruvate, Dlactic acid, Llactic acid and acetic acid as sole carbon sources (Biolog GEN III).
Strain 775 (= NIBRBAC000503087) was isolated from the gut of Leopard mandarin fish (Siniperca scherzeri) at Chungju, Chungcheongbuk Province, Korea. The DNA G + C content of the type strain is 27 mol %.
