Glucoamylase immobilized on acid-hydrolyzed starch graft polyacrylonitrile.
A continuous stirred reactor fed maltose as substrate was used to show that acid hydrolyzed starch-g-polyacry-lonitrile and other polysaccharide graft copolymers can bind and retain significant quantities of active glucoamy-lase. Glucose productivities up to 2.7 g/g carrier/h were observed with the immobilized glucoamylase, and half-lives up to 1800 h were indicative of activity longevity. Fact...
متن کاملMicellization of casein-graft-dextran copolymer prepared through Maillard reaction.
Casein is almost insoluble at around pH 4.6, which is its isoelectric point (pI). Grafting copolymer, casein-g-dextran, was prepared through the Amadori rearrangement of the Maillard reaction. The copolymer has a reversible pH sensitive property: micellization at the pI of casein forming a casein core and dextran shell structure and dissociation when pH differs from the pI. The micelles produce...
متن کاملSaponification of Wheat Straw-g- Polyacrylonitrile
Wheat straw-g-polyacrylonitrile (PAN), containing 40% PAN, was saponified with sodium hydroxide and isolated under three sets ofsaponification and work-up conditions. Each reaction mixture was separated into a water-soluble and a water-insoluble fraction, which were individually analyzed for percentages (by weight) of synthetic polymer (saponified PAN), cellulose, hemicellulose, and lignin. Wat...
متن کاملSimultaneous nanoparticle formation and encapsulation driven by hydrophobic interaction of casein-graft-dextran and beta-carotene.
Casein-graft-dextran copolymer was produced using the Maillard reaction. The copolymer is molecularly soluble in neutral aqueous solution whereas beta-carotene is extremely insoluble. By the method of dialysis or evaporation then dispersing in water, the solubility of hydrophobic complex of casein and beta-carotene decreases whereas the solubility of dextran increases gradually, then nanopartic...
