The amino acid composition of alpha-amylase from Aspergillus oryzae.
o-Amylases have been obtained in crystalline form from a variety of sources covering the animal and vegetable kingdoms. A comparative study of their chemical composition seemed particularly appropriate, since all these enzymes, catalyzing the same chemical reaction, have been shown to possess many common features. The amino acid composition of several cy-amylases has already been described (l-5...
متن کاملAlpha Amylase Production by Aspergillus Oryzae Using Solid State Fermentation
A fungal strain of Aspergillus oryzae was used for the production of alpha amylase by solid state fermentation from agro-industrial waste. Enzyme production was growth associated and maximum activity (8.23 U/ml) were obtained after 120h when incubated at 30°C on wheat bran with initial moisture content 60%; initial medium pH = 5 . Enzyme activity increased when the solid medium was supplemented...
متن کاملInduction and repression of alpha-amylase production in batch and continuous cultures of Aspergillus oryzae.
The intra- and extracellular concentrations of alpha-amylase in Aspergillus oryzae have been measured during batch culture of a wild-type strain and two recombinant strains. The mean intracellular level for the two recombinant strains was about four to five times the level of the wild-type strain. The recombinant strains also had a higher alpha-amylase productivity, whereas the residence time o...
متن کاملTaka-amylase A in the conidia of Aspergillus oryzae RIB40.
A study of Taka-amylase A of conidia from Aspergillus oryzae RIB40 was done. During the research, proteins from conidia and germinated conidia were analyzed using SDS-PAGE, 2-D gel electrophoresis, Western blot analysis, MALDI-TOF Mass spectrometry, and native-PAGE combined with activity staining of TAA. The results showed that TAA exists not only in germinated conidia but also in conidia. Some...
متن کاملRapid induction of alpha-amylase by nongrowing mycelia of Aspergillus oryzae.
A rapid induction system for synthesis of alpha-amylase by the funga Aspergillus oryzae M-13 was established. The mycelia were prepared from 20-h cultures grown on a peptone-glycerol medium and starved for 5 h; maltose was the optimum inducer tested. During h 1 of induction, formation of both intra- and extracellular alpha-amylases occurred at an almost identical rate (70 to 80 microgram/g of c...
