With the aim to improve cellulase production by Trichoderma reesei while trying to reduce its costs, the orthogonal experiments including the pretreatment of wheat straw as substrate instead of microcrystalline cellulose by Phanerochaete chrysosporium and dilute acid were conducted. The result of a volumetric enzyme activity of filter paper activity FPA, 6.11IUmL?1, carboxymethyl cellulase activity CMCase, 29.11IUmL?1 and cellobiase activity(CBA,16.11 IU·mL-1)in the cellulase production under the optimum condition at initial pH5.0 and 30℃ for 48hours with pretreated wheat straw: bran =3:2w:w by Trichoderma reesei showed a highly significant increase of FPA 30.78% , CMCase 26.82% and CBA37.11% compared to previous cellulase production.
