Abstract
|
|
|
|
The aim of the present study was to investigate how the hardness of groundwater affects in the alcohol fermentation. Ozone plays an important role to enhance the water quality, resulting in 85% reduction of hardness, and 30% increase in total glucose produced due to increased conductivity and biodegradability of water. After all, experiments using ozone are presented for the improvement of alcohol productivity. Although initially increased slightly alcohol production, higher than expected ethanol production was observed, with ozone treatment resulting in 20% higher production.
