摘　　要：芽孢杆菌属于革兰氏阳性菌,其主要特征是能够产生抗逆性的内生孢子——芽孢。芽孢能够抵抗多种不良环境,因此较易储存。与乳酸菌、酵母菌等微生态制剂不同,芽孢作为芽孢杆菌主要的商品形式,在动物肠道内的作用方式和机理较为复杂,目前已成为国内外研究的热点。文章对近几年芽孢杆菌在动物肠道中的作用机理及其养殖应用效果进行综述,并对其在养殖业中的应用前景进行了展望,以期为更好地开发和应用此类微生态制剂提供参考。bacillus subtilis sp.belongs to Gram-positive bacteria.Its main characteristic is to produce resistance endospores,which could tolerate a variety of adverse environment.Thus,spores could be easily storaged.Differed from the normal probiotivs like lactiv acid bacteria and yeast,spores are the major commercial form of B.subtilis sp.Because of the mechanism andmode of action of spores are comlicated.it becomes the major concern in researches.In this paper,we summarized the possible mechanisms of spores in animal gut system and also discussed the effects of spores in animal application.We also predicted the trends of its application in agriculture,for a better development and application of this kind of probiotics.
