To reduce the enzyme cost for commercial production of ethanol from cellulosic biomass, synergistic improvement of the following three technologies are quite important: i) Low-cost production of enzymes, ii) Optimization of enzyme cocktail for saccharification, and iii) Recycle and/or reuse of enzymes. In this work, based on the above concept, a method for standardization of evaluation on the efficiency of enzymatic saccharification process has been established. Using this method, performance of a commercial enzyme cocktail for saccharification of ammonia-treated Erianthus has been evaluated and the actual strategy towards reduction of the enzyme cost in our process has been focused.
