直接饲喂微生物和发酵制品生产菌株鉴定概述

Overview of identification of direct feed microorganisms and fermentation production strains

我国生物发酵类饲料添加剂主要涉及两类,即直接饲喂微生物和发酵制品(如酶制剂、氨基酸等)。对微生物进行科学准确的鉴定是开展生物发酵类饲料添加剂安全性评价的基础,也是此类产品研发和产业化发展的必要前提。文章介绍了欧盟和我国直接饲喂微生物和发酵制品生产菌株鉴定要求,分析了形态学、生理生化和分子生物学鉴定技术,并系统阐述了微生物鉴定技术的应用,为开展直接饲喂微生物和发酵制品生产菌株鉴定提供参考。

Biological fermentation feed additives mainly include two types in China,namely,direct feed microorganisms and fermentation production(such as enzymes,amino acids,etc.).Scientific and accurate identification of microorganisms is the basis for the safety evaluation of biological fermentation feed additives,and also the priority for product research and industrial development.This article introduced the identification requirements in European Union and China for direct feed microorganisms and fermentation production strains,analyzed the identification techniques of morphology,physiology,biochemistry,and molecular biology,and systematically expounded the application of microbial identification techniques,which could provide references for the identification of direct feed microorganisms and fermentation production strains.
