Abstract

Abstract:

The fermentation of rumen microorganisms enables ruminants to effectively utilize nutrients such as crude fibers. As a natural fermentation tank of feedstuffs,the rumen supplies important resources for the development of microecological agents,including cellulose,xylan,fat and toxin-degrading bacteria,non-protein nitrogen utilization bacteria and methanotrophic bacteria,etc. However,most of the microorganism in the rumen cannot be cultured,and non-standard artificial culture methods and processes further restrict the development and utilization of rumen bacterial resources. Therefore,based on the existing research progress in the isolation of rumen bacteria at home and abroad,this article summarizes the separation standard steps,the current research status and improvement opinions. It aims to provide a more comprehensive technical reference and an overview of the current situation for the separation of rumen functional bacteria.

Key words: rumen bacteria, isolation and cultivation, techniques
