Abstract

Milk clotting enzyme produced by Rhizomucor miehei NRRL 2034 under solid state fermentation was efficiently immobilized on Tricalcium phosphate (TCP) with immobilization degree of 90 % and activity retained of 93%. Optimum pH value for enzyme immobilization was pH 4. Stirring time of 30 min. was most suitable for the process at 30^oC. 3 mg protein concentration was the best for ideal immobilization. Immobilized enzyme reacted optimally at pH 5 which represents the optimum value for the free enzyme preparation. Optimum temperature raised to 70°C for immobilized enzyme preparation in comparison to 60°C for free enzyme. Immobilized enzyme showed improved thermal stability.
