摘　　要：嗜杀酵母能够分泌嗜杀毒素杀死特定的微生物。将嗜杀酵母作为工业生产用菌株,可以有效防止生产过程中的杂菌污染,净化发酵体系,保证发酵的正常进行;嗜杀毒素还可以制备成为抗真菌剂,用以抵制病原酵母及类酵母等微生物的侵染。综合论述了嗜杀酵母的分类学地位及生物学特性,嗜杀毒素产生和作用的机理,并阐述了环境因素对嗜杀酵母菌自身及其分泌嗜杀毒素的影响。Killer yeast could secrete protein toxin which is lethal to certain microorganism. The use of killer yeast as industrial strains could effectively prevent the contamination of bacteria, purify fermentation system, and ensure normal fermentation. At the same time, killer toxin also could be prepared as anti-fimgal agent to prevent pathogenic microorganisms and yeast-like organisms infection. In this paper, the taxonomic position and biological characteristics of killer yeast, and the production and the mechanism of killer toxins were elaborated. Besides, the effects of environmental factors on killer yeast and killer toxin secretion were also analyzed.
