摘要
瘤胃细菌脲酶和产脲酶菌是尿素利用的基础,影响着反刍动物的肠道健康和氮素平衡。本文综述了脲酶的结构特征及在尿素代谢中的作用、瘤胃产脲酶菌的多样性、瘤胃细菌脲酶活性及其影响因素和脲酶抑制剂在反刍动物中的应用等内容,以期为全面认识瘤胃微生物提供新的方法和思路,为合理调控、提高反刍动物尿素的利用率提供参考依据。
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.
