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.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
