Fed-batch culturing of ethanol forming strain CS4435L for high-titer ethanol production. Fed-batch was performed with initial 80 g/L lactose and 2.5 % (w/v) CSLH in the residual whey permeate medium and 500 g/L lactose stock solution was used for feeding. CSLH was prepared based on H1 condition (CSL treated with 0.05 % H2SO4). Cell density (filled squares), lactose concentration (filled circles), and ethanol concentration (filled triangles) are displayed. Experiments were conducted in duplicate and error bars indicate standard deviations
