Figure 5
SEP rate of electrostatic fermentation under different conditions.
Group 1: Ethanol production is increased as the electrode area is increased from 146 cm2 (Area 1) through 228 cm2 (Area 2) to 308 cm2 (Area 3). Group 2: The effect of initial glucose concentration on ethanol production. Group 3: Similar ethanol production to is obtained using 2-liter fermentation mixture. Group 4: The fermentation performed using cultured S. cerevisiae approaches the ethanol yield on the VHG level.
