SummaryA method for immobilizing yeast cells (Saccharomyces cerevisiae) possessing invertase activity by direct adhesion on tuff granules coated with insolubilized gelatin is described. The immobilized cells, firmly fixed as a monolayer onto the surface of the support granules display catalytic properties (in terms of apparent Km) close to free cells and are particularly suitable for continuous sucrose hydrolysis in a fixed-bed reactor. From an industrial point of view, the immobilization… CONTINUE READING
