Abstract
The effects of electric current on the fermentation characteristics of yeast were investigated. When 10 mA direct current (DC) or 100 mA alt ernating current (AC) was applied to the culture broth, significant in creases in cell growth and alcohol production rates occurred. The cont ents of higher alcohols, esters and organic acids in the culture broth s to which AC and DC were applied, were different from those in the co ntrol culture (no current application). Several compounds such as acet aldehyde and acetic acid, were formed from ethanol as a result of elec trode reaction.
