Abstract
1. The conversion of alcoholic fermentation to glycerol fermentation was achieved by the use of p-benzoquinone as an anticarboxylase substance.
2. After a fractional addition of 20 to 30mg of p-benzoquinone to the culture of 2g yeast in 100ml of 10 per cent glucose medium, a slow fermentation took place lasting for about one week, producing ca. 3g of alcohol and 1.5g of glycerol.
