Comparative studies of the fermentation of cane molasses into ethanol by Saccharomyces cerevisiae in the presence or absence of fungal invertase were performed. When cane molasses was fermented by the yeast at 30 degrees Centigrade and pH 5.0, the presence of the enzyme had no effect on ethanol production. At pH 3.4, ethanol production was increased by the addition of invertase. At 40 degrees C, the addition of invertase increased ethanol production by 5.5% at pH 5.0 and by 20.9% at pH 3.5. (Refs. 8).
