Figure 4From: Engineering glutathione biosynthesis of Saccharomyces cerevisiae increases robustness to inhibitors in pretreated lignocellulosic materialsSpecific ethanol production rates over time in SSF of spruce with the strains investigated in the present study. The specific rates were calculated assuming a cell concentration of 4 g L-1 throughout the whole fermentation course. The bars represent mean values from two independent cultivations. The error bars show the maximum and minimum values.Back to article page
