Abstract: Diacetyl resistant mutant strain was selected through the culture of APV beer yeast strains in gradient culture mediums of different diacetyl content.Then after separation,screening,fermentation,and diacetyl domestication,a strain was finally developed named as 7# strain.Such strain could achieve low temperature fermentation at 11 ℃ with peak value of diacetyl as 0.36 mg/L.And diacetyl content in product beer was 0.06 mg/L and the actual fermenting degree was 66.1 %.(Tran.by YUE Yang)
