Enhanced catalytic features of sol-gel immobilized MnP isolated from solid state culture of Pleurotus ostreatus IBL-02

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 KM, higher Vmax, hyper-activation, enhanced acidic and thermal stability up to 70 ℃, 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）.
