Production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic Gram-positive coccus, designated strain F in basal medium containing peptone from meat, yeast extract, NaCl (7% w/v) and starch. Biochemical and physiological characterization along with 16S rRNA sequence analysis placed F in the genu...

Alkaline proteases are the most important groups of commercial enzymes, which have been broadly used in industrial processes. In this study, Bacillus sp. PTCC 1538 was selected as a biological agent to produce alkaline protease. Enzyme production under submerge fermentation using waste effluent investigated. Since costs raw material plays an role cost enzyme production, corn steep liquor (CSL) ...

Extra-cellular isoamylase was produced by Rhizopus oryzae PR7 in solid-state fermentations of various agro wastes, among which millet, oat, tapioca, and arum (Colocasia esculenta) showed promising results. The highest amount of enzyme production was obtained after 72 h of growth at 28°C. The optimum pH for enzyme production was 8.0. Among the various additives tested, enzyme production increase...

l-asparaginase is a candidate enzyme for anti-neoplastic agent againstacute lymphoblasticleukemia and also extensively use in the food industry for prevention of acrylamide formation. l-asparaginase is widely distributed among microorganisms. in this study, marine bacteria were isolated from persian gulf and screened for l-asparaginase activity. production of l-asparaginase was carried out by u...

production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic gram-positive coccus, designated strain f in basal medium containing peptone from meat, yeast extract, nacl (7% w/v) and starch. biochemical and physiological characterization along with 16s rrna sequence analysis placed f in the genu...

Inducible nitric oxide synthase (iNOS) gene expresses a calcium calmudolin-independent enzyme which can catalyse NO production from L-arginine. The induction of iNOS activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (LPS). Previous studies indicated that all nitric oxide synthases (NOS) activated in human umbilical vein endot...

The present study deals the optimization of cultural conditions for the production of alpha amylase by Aspergillus oryzae IIB-30 and its mutant derivative A. oryzae EMS-18 in stirred fermenter. The time of fermentation for enzyme production by both wild and mutant strains was studied. It was found that the time required for maximal enzyme production (608 U/ml) in case of mutant strain was reduc...
