摘要
采用嗜热脂肪芽孢杆菌作为指示菌,对牛乳中青霉素类药物残留进行检测。采用滤纸片法研究了青霉素钠的检测限以及不同营养组分、不同药物对检测限结果的影响等。结果表明青霉素钠检测限为1 ng/mL,而苄星青霉素的检测限为2 ng/mL;富含大豆蛋白胨和胰蛋白胨的培养基组分更适合嗜热脂肪芽孢杆菌生长,从而便于检测限的测定。
Bacillus stearothermophilus was used as the indicator to detect penicillin residues in milk. Filter paper method was used to study detection limit of sodium penicillin, and the effect of different nutritional components, and different drugs on the detection limit in this paper. The results showed detection limit of sodium penicillin and benzathine penicillin was 1 ng/mL and 2 ng/mL respectively, and culture medium rich in soy peptone and tryptone was more suitable for the growth of Bacillus stearothermophilus, thereby facilitating the determination of the detection limit.
