Ethanol production was not affected when the activity of the former two enzymes was varied within a wide range. By contrast, β-glucosidase markedly affected ethanol production showing an optimum level of 0.7-0.8 unit/ml growth medium. A significant decrease of cellulose bioconversion time to ethanol was obtained when β-glucosidase activity was adjusted to this optimal level at the beginning of the fermentation process.
