Abstract

In order to screen high consistency yeast parent strains of protoplast fusion, Qingdao beer yeast T1, T2 and T3 and high consistency yeast G4, G6 were used as tested strains.By comparing with the indexes in fermentation of 100L, such as yeast quantity, diacetyl change, fermentation degree, acidity, α-N assimilation rate, the result showed that the tested indexes of G4 and G6 were better than the indexes of T1, T2 and T3.Except for cohesion, the other indexes of T1 and T3 were better than those of T2.So, T1, T3 and G4, G6 were fusion parent strains.
