Enzymatic treatment (ET) of thin stillage’s solids with ROHALASE® VISCO-SEP at 44 °C and pH 4.8 (buffer): pentosan recovery yield ηET,p related to total amount of pentosans in the liquid hydrolysate and in the solid residue as well the pentosan solubilisation yield σp (left). Recovery yield of released xylose ηET,x (%) related to the total amount of xylose in the solid (right) (mean values of duplicates; error bars correspond to the standard deviation). a) tR = 0 means a treatment at 44 °C and pH 4.8 (buffer) for 30 min without enzymes
