A combined enzymatic hydrolysis and fermentation (CHF) approach was established for the bioconversion of wood and agricultural residues to butanediol and ethanol. The final butanediol levels obtained from aspenwood xylan or solka floc by the CHF approach were 40-68% greater than the values obtained with the conventional sequential hydrolysis and fermentation approach. The combined cellulose and hemicellulose components of steam-exploded aspenwood and agricultural residues could be directly used by the CHF approach for the production of butanediol and ethanol. The final product yields ranged from 11 to 23 g/100 g original untreated biomass at 34.5-65.4% of the theoretical conversion efficiencies.
