摘要: 畜禽生产中,抗生素的不合理使用在畜禽产品中极易形成抗生素残留超标的安全隐患,不仅威胁人类健康,也制约着养殖业的可持续发展。益生菌正是在这种情况下作为抗生素的有效替代品应用于动物饲料中。但是,有关益生菌制剂发挥益生作用的机理还不是很清楚,而通过现代生物技术对有益菌株进行遗传标记,是研究和阐明其在动物体内作用机理的重要技术手段和有效途径之一。绿色荧光蛋白(green fluorescent protein,GFP)作为新的报告系统,已开始逐渐应用于饲用微生物的动态监测和作用机理研究中,且已表现出良好的应用前景。

Abstract: Irrational use of antibiotics in livestock and poultry production easily cause security risk that antibiotic residues exceed standard in products. This security risk not only threatens human health,but also restricts the sustainable development of livestock and poultry production. Probiotics used as an effective alternative to antibiotics in animal feed in this situation. However,the benefits mechanism of probiotics is not very clear. Using modern biotechnology label beneficial strains is an important technology and effective way to study and explain the mechanism of prebiotics in vivo. As a new reporting system,green fluorescent protein (GFP) has been used in the dynamic monitoring and mechanism study of feed micro-organisms,and has shown good application prospect.

Key words: prebiotics; green fluorescent protein; genetic markers
