✦ Synopsis

Conidia of Penicillium variabile P16 producing glucose oxidase were immobilized in different carriers and used in repeated-batch processes. Limited free-cell growth and good me,:hanical stability of the carriers were obtained with Ca-alginate, agar and polyurethane sponge. During prolonged experiments, the polyurethane sponge appeared to be the best carrier in relation to glucose oxidase and catalase activities. The maximum mean volumetric productivity of gluconate was obtained using agar as immobilizing agent.

## Abstract **Summary:** Gluconic acid was obtained in the permeate side of the bioreactor with glucose oxidase (GOD) immobilized onto anion‐exchange membrane (AEM) of low‐density polyethylene grafted with 4‐vinylpiridine. The electric resistance of the anion‐exchange membranes was increased after
