Two mutants,named mut-1 and mut-2,with decreased ADH activity were screened out by yeast peptone dextrose(YPD)agar medium containing allyl alcohol. These two mutants had decreased ADH activities of 41.63% and 50.29% compared with the parent strain.

• 在含丙烯醇的YPD筛选培养基上筛选获得两株ADH活力降低的突变株mut-1和mut-2；检测突变株mut-1和mut-2的最大ADH活力分别为35.；67和43
