Abstract: In this research, 3 fine yeast strains were selected from Xiangxi natural savory vinegar,and their main production performance about alcohol-producing velocity, alcohol degree resistance, temperature resistance, bottom-nutrition resistance had been investigated to screen uperior yeast strain. The results showed that the NO.9 strain is the best among such production performancs as alcohol-producing velocity, alcohol degree resistance, bottom-nutrition resistance, and can resist large tempera- ture range, so it is the uperior yeast strain.
