Abstract
The use of intergeneric recombinant fungi strains for the degradation of na tural cellulosic substrates gave rise to various degrees of hydrolysis rate s. Pretreating crude cellulose with alkaline or dilute acidic catalysts and heating removed the lignocellulosic fraction that is not attacked by micro bial cellulase system, resulting in higher activity values and hydrolysis r ates than when untreated substrates were used. Pretreated wheat straw was t he best substrate, giving higher hydrolysis rates expressed as glucose ml(- 1) min(-1) by recombinant strain 5-3-1 that exeeded other fungi strains inv estigated.
