INVESTIGATION ON THE PRODUCTION OF L-GLUTAMINASE FROM PSEUDOMONAS STUTZERI STRAIN UNDER SOLID STATE FERMENTATION USING VARIOUS AGRO RESIDUES
Solid state fermentation was carried out for the production of L-glutaminase by Pseudomonas stutzeri PIMS6 using different agro residues including green gram husk, Bengal gram husk, cattle feed, wheat bran and groundnut oil cake as solid substrates. L-glutaminase has received significant attention in recent years owing to its potential applications in medicine as an anticancer agent, as an efficient anti-retroviral agent and as a biosensor. In food industries it is used as a flavor and aroma enhancing agent. The maximum yield (55.24 U/gds) of L-glutaminase by Pseudomomonas stutzeri PIMS6 was obtained using cattle feed at 75% initial moisture content, initial pH 8.0, supplemented with glucose (1.0%), ammonium sulphate (1.0%), Â inoculated with 5% of inoculum and incubated at 37Â°C for 96 h. Both physico-chemical and nutritional parameters played a significant role in the production of the enzyme L-glutaminase.
