摘要
研究了pH值、温度和作用时间对JW-2号蛋白酶活力的影响。结果表明,JW-2号蛋白酶的最适作用温度在65℃左右;最适作用pH值在11左右;随着作用时间的延长,JW-2号蛋白酶的活力逐步下降。
The effects of pH value, temperature and catalysis time on JW-2 protein enzyme activity have been studied in this paper. The result proved that the best catalysis temperature of JW-2 protein enzyme was about 65 ℃ and the catalysis pH value was about 11.0. The activity of JW-2 protein enzyme may decrease if catalysis time is delayed.
