Abstract

Bacterial urease and urease-producing bacteria in the rumen are fundamental in the utilization of urea, which play important roles in gastrointestinal health and nitrogen balance for ruminants. The present review intended to discuss the character of urease structure, the role of urease in urea metabolism of ruminant, the diversity of urease-producing ruminant bacteria, urease activity and factors affecting them, and urease inhibitor and its application in the rumen, which could be useful for providing the methods and ideas for understanding rumen microorganisms comprehensively, and for regulating and improving the utilization efficiency of urea in ruminants.
