摘要
对乳酸链球菌素的最佳分离条件进行了研究,根据分离条件的选择情况,通过对在不同分离条件下产生的乳酸链球菌素产物的活性大小比较,对其效价的检验。通过正交试验确定出最佳分离条件:正丙醇与发酵液的体积比3∶1,提取次数为2次,丙酮与提取液的体积比为4∶1。用DPS软件处理后确定出最后的最佳分离条件。
The best separation condition of Nisin was studied in this paper.Comparing the anti-bacterium bioactivity of Nisin,best separation conditions were obtained: the volume ratio of 1-propanol and the fermentation liquid 3∶ 1,extracting 2 times,the volume ratio of acetone and dosage 4∶ 1.DPS software was used to obtain the best separation conditions of Nisin.
