酶是生物细胞原生质合成且具有高度催化活性的蛋白质。因其来源于生物体,故通常称为“生物催化剂”。我国从1963年到1976年,全国17个省市建起20家工厂,年产量达到3000吨。到1980年,全国酶制剂产量达到8940吨,品种从单一BF-7658增加到12种(淀粉酶1种,中、碱、酶性蛋白酶10种,脂肪酶1种)。改革开放以来,由于 Enzymes are proteins that are bio-protoplasmically synthesized and highly catalytically active. It is commonly referred to as “biocatalyst” because of its origin in living organisms. Our country from 1963 to 1976, 17 provinces and cities across the country built 20 factories, the annual output reached 3,000 tons. By 1980, the national enzyme production reached 8940 tons, the variety increased from single BF-7658 to 12 kinds (1 kinds of amylase, medium, alkali, 10 kinds of enzyme protease, 1 kinds of lipase). Since the reform and opening up, due
