The strain is Gram-negative Brevibacterium, with terminal single flagella, the main biochemical characteristics of oxidase-positive fermentation of acid gas production, fermentation of maltose, lactose, inositol, etc; no fermentation of mannitol, rhamnose, Arab Sugar, etc .; catalase, arginine hydrolase, ornithine decarboxylase, lysine decarboxylase positive. The mouse, quail, crucian carp blood cells without hemolysis, the optimum growth conditions temperature 28 ℃, p H7, containing 1% Na Cl. After a healthy sense of crab, no incidence.
