Study of L-Asparaginase Production by Streptomyces noursei MTCC 10469, Isolated from Marine Sponge Callyspongia diffusa
L-asparaginase is an anti-neoplastic agent used in the chemotherapy of lymphoblastic leukaemia. The present work deals with production of extra-cellular Lasparaginase from marine actinomycetes, using submerged fermentation. Marine actinomycete Streptomyces associated with marine spongeCallyspongia diffusa was isolated using specific ISP medium. Sponge-associated Streptomyces was character...
متن کاملProduction, purification and characterization of l-asparaginase from streptomyces gulbargensis
L-asparaginase is an anti-neoplastic agent used in the lymphoblastic leukaemia chemotherapy. In the present study a novel strain, Streptomyces gulbargensis was explored for the production of extra-cellular L-asparaginase using groundnut cake extract. The optimum pH, temperature, inoculum size and agitation speed for enzyme production were pH 8.5, 40°C, 1x10(8)spores/ml and 200 rev/min respectiv...
متن کاملOxidation of Meloxicam by Streptomyces griseus
The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...
متن کاملCycloheximide production by Streptomyces griseus: control mechanisms of cycloheximide biosynthesis.
Cycloheximide accumulation in a fermentation medium has been shown to be the product of the balance between synthesis and degradation of this antibiotic. Glucose has been shown to prevent cycloheximide degradation. Cycloheximide has been shown to interfere with its own synthesis probably due to feedback inhibition. Approaches for increasing cycloheximide titers in the light of these findings ar...
متن کاملMedium optimization for production of L-Glutaminase (EC 3.5.1.2) by Streptomyces griseus under submerged fermentation
L-Glutaminase is widely distributed in microorganisms including bacteria, yeast and fungi. The enzyme mainly catalyzes the hydrolysis of γ-amido bond of l-glutamine. In this report medium optimization was conducted through one -factor -at -a -time approach for the submerged production of L-Glutaminase by Streptomyces griseus using different additional carbon, nitrogen, amino acids, mineral salt...
