Immobilization of Candida rugosa lipase on MCM-41 for the transesterification of cotton seed oil.

Present study demonstrated the preparation of MCM-41 as a support for the immobilization of Candida rugosa lipase by the physical adsorption technique. The lipase immobilized MCM-41 has been characterized by scanning electron microscopic and FTIR techniques. At pH 6, maximum lipase immobilization (250 mg/g) on MCM support has been observed and the immobilized lipase was employed as biocatalyst ...

Optimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method

Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, w/w), immobilization time (60-120 min) and alcohol percentage (20-40, %v/v) on the specific act...

Efficient Improving the Activity and Enantioselectivity of Candida rugosa Lipase for the Resolution of Naproxen by Enzyme Immobilization on MCM-41 Mesoporous Molecular Sieve

Lipase from Candida rogusa was immobilized on MCM-41 mesoporous molecular sieves in a trapped aqueous-organic biphase system for the resolution of racemic naproxen methyl ester. It was interesting that the activity and enantioselectivity of the immobilized lipase were improved significantly relative to the free enzyme. The proportion of water (ml)/support (g) has a dramatic influence on the act...

Optimization of Lipase-Catalyzed Transesterification of Cotton Seed Oil for Biodiesel Production Using Response Surface Methodology

The aim of this work was to study the biodiesel production from cotton seed oil by lipase produced by Pichia guilliermondii lipase, which was immobilized onto hydrophobic magnetic particles (HMPs). The optimum reaction conditions were determined for lipase dosage, methanol-to-oil molar ratio, temperature and water content. Using response surface methodology, a quadratic polynomial equation was ...

Immobilization of Cobaloxime on MCM- 41

This work reports, immobilization the Cobaloxime [Co (DH) Cl;DH,dimethylglyoximato)] onto the MCM- .The surface of MCM- was initially functionalized with -aminopropyltrimethoxysilane and -pyridine. For the electrostatic immobilization this was reacted with Cobaloxime and immobilization was achieved by an electrostatic interaction between the Co Cobaloxime and the N of the pyridine and NH amine....
