| Abstract: | In this paper, the fermentation properties and genetic stability of high SO2 -producing strain of Saccharomyces cerevisiae were studied. The result of beer fermentation by mutant M8 indicated that its fermentative properties were better. Compared with the original strain S-5, the production of SO2 by the twentieth generation of mutant M8 increased by 20.72%, H2S production was reduced by 49.3%, indicated mutant M8's genetic stability were better. |
