采用滤纸片扩散法分别测定了蛋清溶菌酶和茶多酚对供试菌的抑菌圈直径,并对其抑菌作用的持久性进行了观察与记录。采用对倍稀释的方法,分别测定了单独使用和联合使用蛋清溶菌酶和茶多酚时的最低抑菌浓度(MIC),利用FIC值对两者联合使用后的抑菌效果进行了评价,并确定其最佳复配比例。研究结果表明:蛋清溶菌酶和茶多酚联合使用时,对金黄色葡萄球菌的抑菌效果表现出相加作用,对大肠杆菌及沙门氏菌表现出强烈的相加作用。
採用濾紙片擴散法分彆測定瞭蛋清溶菌酶和茶多酚對供試菌的抑菌圈直徑,併對其抑菌作用的持久性進行瞭觀察與記錄。採用對倍稀釋的方法,分彆測定瞭單獨使用和聯閤使用蛋清溶菌酶和茶多酚時的最低抑菌濃度(MIC),利用FIC值對兩者聯閤使用後的抑菌效果進行瞭評價,併確定其最佳複配比例。研究結果錶明:蛋清溶菌酶和茶多酚聯閤使用時,對金黃色葡萄毬菌的抑菌效果錶現齣相加作用,對大腸桿菌及沙門氏菌錶現齣彊烈的相加作用。

The bacteriostatic circles of the egg-white lysozyme and tea polyphenols were measured by filter paper dispersion, and the bacteriostasis effect of durability was observed. Using the double dilution method, the individual and combined minimum inhibitory concentration (MIC) of the egg-white tysozyme and tea polyphenols were determined respectively. The joint bacteriostasis effects of them were evaluated by FIC value. Then, the best mixed proportions were ensured. The results show that: the combined application of the egg-white lysozyme and tea polyphenols displayed that they had addition effect for staphylococcus aureus and a strong addition effect for escherichia coli with salmonella.
