Sucrose Inversion by Saccharomyces Yeast Cells Immobilized on to Corn Grits


Chemical Engineering, Sharif University of Technology


    Sucrose hydrolysis was carried Out by Saccharomyces strains. The effective rate of reaction was examined experimentally for 5 different Saccharomyces strains. Two Strains of Schizosaccharomyces and Saccharomyces Carlsbergensis showed the best invertase activity. These two strains showed Michaelien Kinetics in the sucrose concentration up to 0.2 M and inhibitory effect in the concentration beyond 0.2 M.     These two strains were immobilized on to corn - grits by an adsorption technique. Immobilization of Saccharomyces carlsbergensison to corn - grits by adsorption was found to obey a first order reaction. Sucrose hydrolysis was studied in a continuously immobilized cell reactor.
