Figure 3From: Impact of osmotic stress and ethanol inhibition in yeast cells on process oscillation associated with continuous very-high-gravity ethanol fermentationImpact of exogenous ethanol on continuous ethanol fermentation by S. cerevisiae . Ethanol was supplemented into the LG medium containing 120 g/L glucose at concentrations of 30 g/L (a), 50 g/L (b) and 70 g/L (c), respectively. The media were fed into the fermentation system at the same dilution rate of 0.027 h-1. Arrows indicate the start and end of the feeding of the ethanol-added medium.Back to article page
