A Review on Microbial Alkaline Proteases
Alkaline prorcasex are of considcruhlc interest in view of their activity and stability at alkaline pll. This review describes the protcascs that can resist extreme alkaline environments produced by a wide range of ulk alophilic microorg anisms. Different isol.uion methods which enable the screening and selection of promising organisms 1'01' industrial production are discussed. The various nutr...
متن کاملCharacterization of extracellular alkaline proteases and collagenase induction in Vibrio alginolyticus.
The number and approximate molecular weights of extracellular alkaline proteases produced by Vibrio alginolyticus were determined by gelatin-PAGE. Three major bands of protease activity with apparent molecular weights of approximately 28 000, 22 500 and 19 500 (proteases 1, 2 and 3, respectively) and two minor bands of protease activity with apparent molecular weights of approximately 15 500 an...
متن کاملCharacterization of thermostable alkaline proteases from Bacillus infantis SKS1 isolated from garden soil
Proteases are one of the largest groups of hydrolytic enzymes constituting about 60% of total worldwide sales of industrial enzymes due to their wide applications in detergent, leather, textile, food and pharmaceutical industry. Microbial proteases have been preferred over animal and plant proteases because of their fundamental features and ease in production. Bacillus infantis SKS1, an alkalin...
متن کاملPartial Purification of Mucor pusillus Intracellular Proteases.
The intracellular protease extracted from the freeze-dried mycelia obtained after the growth of Mucor pusillus at 30 degrees C in corn steep liquor medium was chromatographed on DEAE-A50. Some characteristics of the protease fractions obtained after ion-exchange chromatography were determined and compared with those of the extracellular proteases reported previously. The mycelia were found to c...
متن کاملProperties of two homologous alkaline proteases from Streptomyces rectus.
Some physicochemical properties of two thermostable proteases from Streptomyces rectus are described. The enzymes were judged to be identical with respect to molecular weight, inactivation with serine protease inhibitors, and in primary structure by peptide analysis. Amino acid analysis indicated the enzymes had identical compositions except for their amide content. The molecular weights of the...
