A strain HH407 which could production cold-active alkaline protease, was isolated from the sea area of Lianyungang. Then, the identification and physiological characterization of the strain HH407 were studied. The results showed that the strain HH407 was gram negative, rod shaped, aerobic, with a single polar flagellum, neither endospore nor capsule formed, about 0.4~0.7 μm×1.0~1.8 μm in size. The colony on screening medium were circular, yellow color, smooth, translucent, convex with regular edges.
