Hashem and Darwish (2010) observed that production of ethanol by S. cerevisiae y-1646 was favoured at 35°C temperature and reached its maximum value (5.29 g/l) after 36 h. At 37°C, ethanol production was reduced to 4.38 g/l.
Rani et al. (2010) observed that maximum ethanol content of 56.8 g/l was recorded after 48 h of fermentation at 30°C.
