Abstract:
Enzyme (uricase or invertase) was entrap-immobilized in gel fibre of cellulose acetate-TiO2 by using a gel formation of cellulose acetate and titanium iso-propoxide. The fibre is stable in common solvents, phosphate solution and electrolyte solution over a wide range of pH 4-10. The pH maximum of activity shifts to a more alkaline side compared to free enzyme, reflecting an amphoteric property of TiO2.
