EVALUATION OF EXTRACTIVE BATCH ETHANOL FERMENTATION AT HIGH TEMPERATURE WITH CO2 STRIPPING
In the present work, it was evaluated the removal of ethanol during an extractive batch fermentation at high temperature with CO2 stripping. A conventional batch fermentation (40 °C) (without ethanol removal) was performed as control experiment and, subsequently, an extractive fermentation at 40 °C with ethanol removal by CO2 stripping was carried out. It was verified an increase in the ethanol productivity of 41.4% compared to the conventional fermentation. Thus, the ethanol removal from the fermentative broth at 40 °C showed as an alternative to decrease the inhibitory effect of ethanol on yeast.
