【 摘 要 】

Naturally, snakehead fish (Channa striata) is a prodigious carnivore feeding mainly on live animals, including small shrimp. Based on its feeding habits, the digestrive tracts of snakehead is considered as auspicious source of various enzumes including chitinase. The purpose of this study was to partially characterize chitinase enzyme isolated from digestive tract of snakehead fish. Two parts of digestive tract, stomach and intestine were used as enzymes' source. The results showed that chitinase activity from the stomach was higher than chitinase activity from the intestine. The pH and temperature optimum of chitinase activity from digestive tract (the stomach and the intestine) were 6.0 and 70 °C, respectively.
