Experimental configurations used to investigate the fermentation of steam-pretreated wheat straw. (A) Config. 1, separate hydrolysis of the whole SPWS slurry and co-fermentation of glucose and xylose in the SPWS hydrolysate fed with wheat-starch hydrolysate (or with glucose solution). (B) Config. 2, co-fermentation of glucose and xylose in the liquid fraction of SPWS, which was fed with the mixed hydrolysates of SPWS hydrolysate and wheat-starch hydrolysate, (or with glucose solution).
