Figure 4From: Ethanol production from mixtures of wheat straw and wheat mealVariation in ethanol concentration with time during simultaneous saccharification and fermentation (SSF) of steam-pretreated wheat straw (SPWS), presaccharified wheat meal (PWM) and mixtures of the two (A to D). PWM to SPWS ratios in the mixtures A to D were 0.8:4.2; 1.5:3.5; 2.0:3.0 and 2.5:2.5, respectively.Back to article page
