摘要
通过对解脂假丝酵母ＡＳ２．１４０５胞外脂肪酶粗酶制剂性质的研究，得到了此酶的最适反应温度为４０℃，最适ＰＨ７．５。研究了重金属离子对脂肪酶活力的影响，发现Ｓｒ２＋、Ｂａ２＋对酶有激活作用，Ｃｕ２＋对酶有抑制作用。
The optimum conditions of degrading fat yeast(AS2. 14O5) lipase were temperature of 40℃ and PH7. 5 when the properties of this kind enzyme preparation was studied. By researching into the ef- fect of heavy metal ions on the activity of the lipase, Sr2+ and Ba2+ have been found to activate the lipase, but Cu2+ has been found to inhibit it.
