摘要
纤维体是指某些厌氧细菌和真菌产生的降解纤维素的多酶复合体,它能够将纤维素和微生物细胞连接起来,进而实现对纤维素的高效降解。纤维体首先是在嗜热纤维梭菌上发现并被提出。目前,纤维体的研究已成为瘤胃微生物研究领域的热点问题。本文对纤维体概念的提出过程、纤维体存在的证据、纤维体作用的分子基础和功能以及瘤胃微生物纤维体类似物的研究进行了综述。
Cellulosome refers to a kind of multi-enzyme complex produced by the anaerobic microbes, which can connect the microorganism with cellulose and thereby effectively catalyze the degradation of crude fibre. It has been found and presented in Clostridium thermocellum. In recent years, rumen microbiologists have put increasing efforts on the study of cellulosome of rumen microbes. In this article, based on the latest literature, the development of the concept, the evidence for the presence of cellulosome, the molecular structure of cellulosome and its function, and the study on cellulosome-like structure in the rumen are respectively reviewed.
