Abstract:Summary L-Sorbose was converted to 2-keto-L-gulonic acid by mixtures ofGluconobacter melanogenus IFO 3293 andPseudomonas syringae NRRL B-865 entrapped simultaneously in polyacrylamide gel. Since the temperature optima of both enzymatic reactions involved differed, a two-stage process with cells immobilized separately seems to offer a more efficient method to prepare 2-keto-L-gulonic acid.For preceeding paper in this series see Martin & Perlman (1976).
