微生物源蛋白酶筛选及调控技术研究进展

Research progress on screening and regulation of microbial protease

微生物源蛋白酶由微生物培养发酵获得,具有专一性强、生产工艺简单、成本低、安全高效等特点。在饲粮中添加微生物源蛋白酶可以促进动物对蛋白质的吸收利用,提高动物生长性能,降低饲粮中抗营养因子的抑制作用,改善肠道健康,提高机体免疫力。文章介绍微生物源蛋白酶的分类及特点,论述饲用产蛋白酶微生物的筛选及条件优化,分析微生物源蛋白酶的动物营养调控技术,以期为微生物源蛋白酶在动物养殖生产中的应用提供参考。

Microbial protease is obtained by microbial culture and fermentation, which has the characteristics of strong specificity, simple production process, low cost, safety and efficiency. Adding microbial protease in feed can promote the absorption and utilization of protein by animals, improve animal growth performance, reduce the inhibition of anti nutritional factors in feed, improve intestinal health, and improve body immunity. The paper introduces the classification and characteristics of microbial protease, discusses the screening and optimization of feed protease producing microorganisms, and analyzes the animal nutrition regulation technology of microbial protease, to provide reference for the application of microbial protease in animal production.
