The successful utilization of cellulosic materials depends on the development of economically feasible processes for the literation of low molecular weight soluble products from the polymers. These soluble products, such as hexoses and pentoses, can then be utilized as substrates for the microbial or chemical product of fuels, food, and chemical feedstocks. In the enzymatic saccharification of cellulose, one of the major roadblocks to the development of commercially attractive processes has been the instability of the cellulase complex. It is desirable, for example, to operate the conversion systems at elevated temperatures, but environments with high thermal energy can significantly shorten enzyme half life. The authors have isolated a strain of the fungus Thielavia terrestris that possesses a complete cellulase system, and its enzymes were found to have remarkable thermal stability. The author presents a comparison of the activities of the T. terrestris enzymes with those of Trichoderma reesei.
