本文参照国家食品安全风险评估中心培训的方法,采用对青霉素类药物绝对敏感的标准菌株,利用舒巴坦特异性抑制β-内酰胺酶的活性,并加入青霉素作为对照,通过比对加入β-内酰胺酶抑制剂与未加入抑制剂的样品所产生的抑制圈的大小来间接测定样品是否含有β-内酰胺酶类药物,建立乳及 In this paper, reference to the National Center for Food Safety Risk Assessment training methods, the use of standard strains of penicillin drugs are absolutely sensitive, the use of sulbactam specific inhibition of β-lactamase activity, and add penicillin as a control by adding β- Lactam enzyme inhibitor and the inhibitor-free sample generated inhibition loop size indirect determination of whether the sample contains β-lactamase drugs, the establishment of milk and
