摘要
采用4种蛋白酶对废水鱼汁中蛋白质进行水解,以选择适于废水鱼汁水解的蛋白酶,并对适合废水鱼汁水解的蛋白酶水解条件进行研究。结果表明:中性蛋白酶是最适合水解废鱼汁中蛋白质的工具酶;中性蛋白酶水解鱼汁中蛋白质的最佳条件为:pH 7．5．温度55℃,酶用量400 U·g^(-1)(蛋白质),底物浓度100 mg·g^(-1),水解时间6 h。
Four proteases were used to study the hydrolysis of the waste water of the fish extract and the suitable protease was selected. The optimal hydrolysis condition was also studied. The results showed that the neutral food protease was the most suitable tool enzyme and the best hydrolysis conditions of the neutral protease were as follows： the substrate density was 100 mg · g^-1 under the pH value 7.5 at the temperature of 55 ℃ and the enzyme dosage was 400 U per gram protein with 6 hours hydrolysis.
