ADSORPTION OF INVERTASE.

Method for immobilizing invertase by adsorption on Dowex® anionic exchange resin

This communication describes a method for adsorbing the invertase (EC.3.2.1.26) on DOWEX® anion exchange resin. Among the types of DOWEX® resins studied (1x8:50-400; 1x4:50-400 and 1x2:100400), 1X4-200 was the most suitable, because it adsorbed the invertase molecules completely and the complex 1X4-200/invertase retained 100% of the catalytic activity. Moreover, no leakage of enzyme from the su...

Immobilized invertase.

Invertase is a commercially important enzyme used for the hydrolysis of sucrose. The hydrolysis of sucrose yields an equimolar mixture of glucose and fructose, known as invert syrup, is widely used in food and beverage industries. This enzyme is also used for the manufacture of artificial honey, plasticizing agents used in cosmetics, pharmaceutical and paper industries as well as enzyme electro...

Transglucosidation by honey invertase.

In an investigation of the minor sugars of honey at this laboratory, examination by paper chromatography indicated that several oligosaccharides are present. These have not yet been identified. Since honey is the product of the reaction of honeybee (1) invertase with nectar sugars [sucrose, glucose, and fructose (2)], a comparison is being made of the sugars of honey with the oligosaccharides p...
