摘要
实验对管碟法测定纳他霉素的各项参数进行了研究并量化控制。首先从16种酵母菌中筛选出最利于检测的一种酵母菌,并确定了酵母菌浓度。纳他霉素含量与抑菌圈直径平方呈良好的线性关系,回归方程为y=0.0013x-1.3369(R2=0.9965)。利用此回归方程对纳他霉素进行检测,最小检测浓度为0.1g/L,最大检测浓度为1.5g/L。
The parameters of agar diffusion method for determining natamycin was investigated and controlled in quantification. The results showed that there is a good linear relationship between content of natamycin and diameter square of inhibition zone, and the regression equation is y = 0.0013x - 1.3369 (R^2= 0.9965). The detection range of this method is 0.1 g/L to 1.5 g/L.
