Immobilization of <i>Pseudomonas</i> <i>sp.</i> KLM9 in Sodium Alginate: A Promising Technique for L-Glutaminase Production

Abstract

Microbes and process development are gaining considerable importance owing to their exploitation and suitability for the production of the enzymes of therapeutic and industrial significance. In the present study attempts were made to immobilize the Pseudomonas Sp. KLM9 in different supporting matrix to analyze the possible enhancement in the production of L-Glutaminase. The consequences of the study reveal that, sodium alginate at 3.5% concentration was found to be the better supporting matrix than the others. Further, initial pH 7 of the incubation media, incubation temperature of 37°C were supported good yield of L-Glutaminase by immobilized Pseudomonas Sp KLM9. The fermentation period was reduced to 36 hr with immobilized cells. There is moderate increase in the production L-Glutaminase by the immobilized cells than the free cells of Pseudomonas Sp KLM9. Biomass obtained from the 18 hr old culture of Pseudomonas Sp KLM9 was found better to immobilize for the production of L-Glutaminase.
