摘　　要：目的研究双歧醋对常见病原菌的生物拮抗作用及影响因素。方法采用纸片扩散法(K-B法)、琼脂打孔法和试管稀释法(M IC法)测定双歧醋及其处理物(加热、不同pH)对常见病原菌的拮抗作用,并讨论pH、加热对拮抗作用的影响,同时用某市售醋作为对照。结果双歧醋及其处理物均具有一定的抑菌作用。结论双歧醋对常见病原菌有一定的拮抗作用,抑菌作用强于市售醋。Objective To explore the biological antagonism of bifidobacterium vinegar against common pathogens and influential factor.Method The disk diffusion test（K-B）,agar-well diffusion test and minimal inhibitory concentration test（MIC） were used to study the antagonism of Bifidobacterium vinegar and its treated material（heated and different pH） on common pathogen bacteria in vitro,with certain brand vinegar as the control.Result Bifidobacterium vinegar and its treated material showed certain level of antagonistic activities against pathogens.Conclusion Bifidobacterium vinegar possesses antagonistic activities against common pathogens and exhibits higher activity in comparison with the control.
