---------------------------------
    Various aspects of alcohol fermentation from cellulosic biomass have been discussed thus far. A number of problems still remain to be resolved prior to industrial-scale production of fuel alcohol from cellulosic biomass. As mentioned in the introduction to this chapter, subsequent to our studies on basic and elemental techniques, an integrated pilot plant for the production of alcohol from biomass, was constructed in our laboratory, in order to demonstrate individual processes. Construction of the plant commenced in 1983, and continued in a step-wise manner for 5 years. The final plant was capable of treating 720 kg of raw material per day with the production of 150 to 200 liters of dehydrated fuel alcohol.
