文摘

An indigenous and industrially important manganese peroxidase (MnP) isolated from solid state culture of Pleurotus ostreatus IBL-02 was 2.1-fold purified and immobilized using sol-gel matrix of trimethoxysilane and proplytetramethoxysilane. Lower K_M, higher V_max, hyper-activation, enhanced acidic and thermal stability up to 70 ¡ãC, were the improved/enhanced catalytic features of the presently sol-gel immobilized MnP. A maximum of 100 % decolorization was achieved within a short time period for the different real dyes containing textile industry effluents i.e. Nishat textile (NIT), K&N textile (KIT), Sitara textile (SIT), and Crescent textile (CRT).
