Immobilization of Plant Esterase Purified from Wheat Flour on Porous Poly (GMA-AM-EGDMA) Polymer Particles Newly Made With Liquid and Solid Pore-Forming Reagents
The Poly (GMA-AM-EGDMA) macrospheres were synthesized with glycidlymethacrylate (GMA), acrylamide (AM) as monomer and glycol dimethacrylate (EGDMA) as cross-linker, firstly with carbinol and distilled water as liquid pore-forming reagents and nano-calcium carbonate as solid one via suspension polymerization. Its exterior form was shown by scanning electron microscopy. Under the most suitable te...
متن کاملPRODUCTION OF BETA-GALACTOSIDASE IN SUBMERGED MEDIA BY ASPERGILLUS ORYZAE, PTCC 5 163
Different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by Aspergillus oryzae in submerged fermentation. Enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. Further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. Res...

15 صفحه اولPARTIAL PURIFICATION AND CHARACTERIZATION OF B-GALACTOSIDASE FROM ASPERGILLUS NIGER UV-5
The enzyme pgalactosidase from a mutant strain of A. niger UV-5 was partially purified using ammonium sulfate and acetone. The saturation range of 60-80% ammonium sulfate was found to yield 60.5% enzyme recovery with 2.4 fold purification. Acetone precipitation at enzyme: acetone ratio of 1 : 1.5 brought about a higher yield i.e. 68% and three-fold purification. The combined procedures of ...
متن کاملPurification, Immobilization andCharacterization of Lipase Isoenzyme from Aspergillus niger with C8 Magnetic Particles
The purification of a lipase isoenzyme from an Aspergillus niger lipase A is reported in this manuscript. Purification was carried out in a simple adsorption step, in which the lipase was offered at low ionic strength to the commercially available C8 modified magnetic particles, MaKProt C8. When the isoenzyme was desorbed with a 0.2% solution of Triton X-100, the SDS-PAGE gel showed a single pu...
