By keeping in mind the extensive industrial applications of cellulase, this study was performed to immobilize the indigenous enzyme produced from Trichoderma viride under pre-optimized SSF of an agricultural waste material, wheat straw. To enhance the bio-catalytic and tolerance properties of the present enzyme gel matrix immobilization engineering was applied. Previously, 2.33~fold purified novel cellulase was immobilized in to a xerogel matrix of TMOS and PTMS. FTIR spectroscopy confirmed the successful immobilization of cellulase. The free and immobilized cellulase was characterized and stability profile showed that after 24 h incubation, immobilization enhanced the thermo-stability up to 75% against 80℃ as compare to the free enzyme. Xerogel matrix immobilization enhanced the catalytic efficiency of entrapped enzyme than that of the free cellulase. Among activators/inhibitors SDS, EDTA, and Hg2+ showed inhibitory effect while, gel matrix immobilization enhanced 80% tolerance capacity of the cellulase against inactivating agents.展开更多
