Abstract: Numerous enzymes are used in various types of industries, and one such enzyme used in several of these industries is proteases. Aforementioned, industries such as dairy, detergent, leather, fermentation and several other industries are benefitted with protease enzyme. In the present study, the efficiency of protease production was studied by enriching and immobilizing several matrices by a gram negative bacteria known as Pseudomonas aeruginosa .The immobilization was carried out by four different matrices under two different concentrations of 3% and 4%.Yielded results revealed highest enzymatic activity of 240 (U/ml) in 3% calcium alginate. Still, second highest enzymatic activity of 230 (U/ml) was seen in 4% calcium alginate. On the contrary, free microbial cells showed an enzymatic activity of 100 (U/ml). The peak activities for other methods area as follows: 4% calcium alginate – 133 (U/ml), 3% agar-agar – 100 (U/ml), 4% agar-agar – 91 (U/ml), 3% Gelatin – 85 (U/ml), 4% Gelatin – 88 (U/ml) and Polyacrylamide – 104 (U/ml). The most optimum matrix for the cellular entrapment of Pseudomonas aeruginosa is seen in 3% calcium alginate for alkaline protease production.
