Result Both mutanolysin and lysozyme could successfully lyse the wall of bifidobacterium and extract the plasmid from Bifidobacterium.

结果发酵液与溶酶均成功提取到质粒。

When the denatured reduced egg white lysozymes were renatured by dilution method, an observable amount of aggregate precipitate could be immediately formed.

当复性液稀释复性原服变性蛋白溶酶时，会迅速产生可观量的沉淀。

Method Bifidobacterium plasmid was extracted by mutanolysin from Streptomyces globisporus which could lyse the wall of bifidobacterium.The result was compared with that by lysozyme.

方法利发酵产生的变溶素来消化双歧杆细胞壁，提取质粒，并与商业化溶酶法比较。
