青贮饲料的优良乳酸菌及其应用

Excellent Lactic Acid Bacteria for Silage and Their Application

青贮处理是一种能有效保存饲料营养物质重要存贮方式。青贮发酵是一个十分复杂的微生物活动体系,能否有效控制发酵过程是青贮能否成功的关键,而通过添加优良青贮乳酸菌可以合理地调节青贮内的微生物区系,达到控制发酵过程提升青贮品质的目的,筛选优良乳酸菌有助于促进青贮发酵,推动青贮产业快速发展。本文基于国内外对优良青贮乳酸菌种筛选及利用的相关研究,围绕青贮饲料的优良乳酸菌的类型、作用机制、功能、分离筛选以及应用等方面进行综述,并对其未来的发展提出建议和展望,以期为后续筛选优良菌种和开发优质乳酸菌制剂提供参考。

Silage is an important storage method which can effectively preserve feed nutrients.Silage fermentation is a very complex microbial activity system,whether the fermentation process can be effectively controlled is the key to the success of silage.By adding excellent lactic acid bacteria in silage,the microbial flora in silage can be reasonably adjusted to control the fermentation process and improve the quality of silage,and thus to screen excellent lactic acid bacteria for promoting the rapid development of silage industry.Therefore,based on the researches on the screening and utilization of excellent silage lactic acid bacteria at home and abroad,this paper summarized the types,action mechanism,separation and screening,and application of excellent lactic acid bacteria in silage,and put forward suggestions and prospects for its future development,aiming to provide some reference for the subsequent screening of excellent lactic acid bacteria and the development of high-quality lactic acid bacteria preparation.
