| Abstract: | The use of intergeneric recombinant fungi strains for the degradation of natural cellulosic substrates gave rise to various degrees of hydrolysis rates. Pretreating crude cellulose with alkaline or dilute acidic catalysts and heating removed the lignocellulosic fraction that is not attacked by microbial cellulase system, resulting in higher activity values and hydrolysis rates than when untreated substrates were used. Pretreated wheat straw was the best substrate, giving higher hydrolysis rates expressed as glucose ml–1 min–1 by recombinant strain 5–3-1 that exeeded other fungi strains investigated. |
