kinetics of alkaline protease production by streptomyces griseoflavus ptcc1130
background and objectives: proteases are a group of enzymes that catalyze the degradation of proteins resulting in the pro- duction of their amino acid constituents. they are the most important group of industrial enzymes which account for about 60% of total enzymes in the market and produced mainly by microorganisms. the attempts were made to study the kinetic parameters of protease produced b...
متن کاملBatch Kinetics and Modeling of Alkaline Protease Production by Isolated Bacillus sp. (RESEARCH NOTE)
The aim of this study was the use of fish waste hydrolysate (FWH) as a substrate for alkaline protease production using isolated Bacillus sp. in a batch system. Then the fermentation kinetics of enzyme production was studied. The results show that with the addition of FWH to the fermentation medium with a final concentration of 4% (optimal concentration), alkaline protease value reached a maxim...
متن کاملOptimization of Production Protocol of Alkaline Protease by Streptomyces pulvereceus
Extra cellular alkaline protease producing species is an isolate from soil which was characterized and identified as Streptomyces pulvereceus MTCC 8374. Studies on submerged fermentation revealed that maximum level of enzyme production was during early stationary phase. Optimum pH, inoculum and temperature were 9.0, 3 percent and 33 C respectively. Among carbon sources 0.3 peccent starch gave a...
متن کاملProduction, Purification and Characterization of an Alkaline Protease from an Alkaliphilic Bacillus Sp
An extracellular serine like alkaline protease was purified and characterized from alkaliphilic Bacillus sp. The enzyme was purified to the homogeneity by a combination of aqueous two-phase system and affinity chromatographic techniques. The apparent molecular weight was estimated as 26-29 kDa based on SDS-PAGE and gel filtration chromatography and the enzyme appeared to be a monomer. The Km an...
