doi:10.13560/j.cnki.biotech.bull.1985.2021-0806

Abstract

Abstract:

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.

Key words: silage fermentation, excellent lactic acid bacteria, function, isolation and screening, application
