Saccharomycetes not producing carbon dioxide and producing lactic acid

Abstract

The invention relates to the field of saccharomyces cerevisiae fermentation, in particular to saccharomyces cerevisiae which does not produce carbon dioxide and produces lactic acid. The invention provides saccharomyces cerevisiae which does not produce carbon dioxide, ethanol and lactic acid under anaerobic fermentation conditions. The growth rate of the saccharomyces cerevisiae is higher than that of the known saccharomyces cerevisiae which does not produce ethanol and produces lactic acid. The strain grows vigorously, the generation time reaches 3.5 h and is increased by 20% compared with the generation time of 4.4 h of an original strain, carbon dioxide is completely not produced during anaerobic fermentation, and the conversion rate from glucose to lactic acid and the yield of lactic acid are both remarkably or extremely remarkably increased.
