【摘要】 通过对培养基、水份含量、氮源、培养时间、培养基的起始PH以及培养温度的研究，测定TrichodermareeseiGAB纤维素酶的C₁酶和Cx酶的酶活，找到了一个最佳的条件，即：稻草粉：花生壳=4：1，物料：水份=2：3，以NH₄Cl、（NH₄）₂SO₄、NH₄H₂PO₄为氮源，起始pH为自然pH（约5．8），在28℃下培养84～96h，其酶活性为最高，达到C₁酶为58．2μ，Cx酶为1500μ。同时，也找到了减少生产成本的一条途径。更多还原

【Abstract】 The factors including media, warer contents, nitrogen sources, cultural tine, originalpH and cultural temperatures were studied for producing cellulase by Trichoderma reesei GAB,The results showed that the best condition are f the ratio of material and water equals 2:3, thebest nitrogen sources are (NH4)2SO4, NH4Cl and NH4H2PO4, the original pH is natural pH, andthe cultural bine is 84-96 hours, the cultural temperature is at 28℃. The results showed thatcultured at that condition the cellulase C1 is 58.2μ and the cellulase Cx is 1500μ.更多还原
