摘要
反刍动物瘤胃内尿素分解菌种类多样,探究瘤胃内尿素分解菌组成、了解瘤胃内脲酶活化模式可以为减缓尿素分解速率、提高尿素利用率提供基础。本文综述了基因水平、mRNA水平和蛋白质水平上尿素分解菌的多样性以及高丰度脲酶内辅助蛋白的活化模式,为了解瘤胃内尿素水解过程、针对性开发脲酶抑制剂提供参考。
There are various types of ureolytic bacteria in ruminants.Exploring the composition of ureolytic bacteria and understanding the activation mode of urease in rumen can provide a basis for slowing down urea decomposition rate and improving urea utilization efficiency.The paper reviews the diversity of rumen ureolytic bacteria on the gene level,mRNA level and protein level,respectively,and the activation pattern of auxiliary proteins in rumen high abundance urease,so as to provide a reference for understanding the process of urea hydrolysis in the rumen and developing targeted urease inhibitors.
