Description Two ethanol tolerant yeast isolates of Saccharomyces cerevisiae Y-10 and Saccharomyces cerevisiae Y-7 were compared for their invertase (EC 3.2.1.26, β-fructofuranoside fructohydrolase) and alcohol dehydrogenase (ADH, EC 1.1.1.1, alcohol:NAD oxidoreductase) activities as well as ethanol productivity. The isolates showed significantly higher ethanol productivities compared to the standard strain Saccharomyces uvarum and other yeast strains tested. The alcohol dehydrogenase activity was 40–100% higher in the isolates than S. uvarum and the percentage change varied depending on the growth conditions. However, this was not true for invertase activity. Both the isolates showed a similar ADH isozyme pattern in contrast to S. uvarum. The results suggested that a better correlation between ADH activity and ethanol productivity could be drawn only after extensive studies on the kinetic parameters of the individual isozymes.
