丁酸梭菌的生物学功能及其在水产养殖中的应用研究进展

The biological function of Clostridium butyricum and its application in aquaculture

丁酸梭菌作为一种新型的微生物饲料添加剂,在畜禽养殖中的研究及应用较多,但在水产养殖中的应用研究仍处于起步阶段。丁酸梭菌在水产养殖动物中具有维持消化道微生态平衡、改善肠道上皮组织的健康状况、提高机体免疫力和促进营养物质的消化吸收等功能。本文主要对丁酸梭菌的生物学功能及其在水产养殖中的应用研究现状进行综述,并指出其作为水产饲料添加剂在应用中存在的问题,同时对其未来发展前景进行了展望。

Clostridium butyricum is a gram-positive,obligate anaerobic and endospore-forming probiotic,which has a high adapting ability to higher temperature and lower pH.As a new kind of microbial feed additive,it has been studied and applied in livestock and poultry breeding,but its application in aquaculture is rarely reported.C.butyricum has the function of maintaining the ecological balance in digestive tract,repairing the intestine epithelium,improving the immunity of the organism and promoting the absorption of nutrients in aquaculture.In this paper,we reviewed advances in the biological function and the application in aquaculture of C.butyricum,and pointed out problems during the application of C.butyricum as feed additive.Some advices were also put forward for further research of C.butyricum.
