Structures of Cellulosic Materials and their Hydrolysis by Enzymes

  • G. T. Tsao


Annual availability of low-valued cellulosic materials in the United States has been estimated to be about one billion tons (dry weight). This figure does not include high-valued cellulosic products such as textile, pulp, lumber and plywood. About 20% of the low-valued cellulosic materials can be collected at a reasonably low cost to support production of chemicals. The 200 million tons of biomass represents about 1.0 x 1015 kilobalories of energy. This is a significant natural resource. For instance, assuming that 25% of this energy can be converted into that of ethanol, a total of about 35 billion liters of anhydrous ethanol can be produced to meet a part of our liquid fuel.
