The current studies involved a series of chemical treatment combinations upon wheat straw (WS), and subsequent hydrolysis of released cellulose to fermentable sugars. Primary chemical treatment of WS was followed by additional, secondary treatment of residues with either acids or alkali. Following primary and secondary treatment the WS residues were hydrolyzed with cellulase, and final glucose yields were determined. Samples of residues and effluents taken after each reaction also were analyzed. Large-scale experiments for both saccharification and alcohol production were investigated in a glass-column reactor. The results showed that conversion of the cellulosic component to sugar varied with the chemical modification steps. 23 refs.
