Since sulfur dioxide is used in winemaking to inhibit the growth of microorganisms, its effect on the activity of Sch. pombe during fermentation was studied to determine the effect of various concentrations of SO/sub 2/ on the activity of this yeast, in comparison with that of the Saccharomyces cerevisiae. Schizosaccharomyces pombe was more resistant to sulfur dioxide than Saccharomyces cerevisiae in wine fermentation. Sch. pombe was as active in the presence of 300 ppm added SO/sub 2/ as Sac. cerevisiae was in 100 ppm added SO/sub 2/. Utilization of malic acid by Sch. pombe was rapid and complete, and was not affected by 300 ppm added SO/sub 2/. The only effect noted was the slower starts with the higher SO/sub 2/ concentrations. In a mixed culture of Sch. pombe and Sac. cerevisiae, the Sch. yeast was not overgrown by the Sac. yeast when 150 ppm or more of SO2 was added. 12 references, 5 tables.
