Figure 4From: Simultaneously improving xylose fermentation and tolerance to lignocellulosic inhibitors through evolutionary engineering of recombinant Saccharomyces cerevisiaeharbouring xylose isomeraseFed-batch SSF culture using steam-pretreated sweet sorghum bagasse. Single fed-batch SSF experiments of pressed solids fed-batch using S. cerevisiae strains D5A+H(A) and TMB 3400 (B). Figure symbols: ethanol (diamonds), glucose (circles) and xylose (triangles). Arrows indicate the addition of substrate in 2.5% (g/v) increments at 0, 24, 48 and 72Â h.Back to article page
