ABSTRACT Calcium alginate and kappa‐carrageenan were evaluated as entrapment matrices for whole cells of Schizosaccharomyces pombe. The fermentation activity of immobilized cells was enhanced by preincubation in nutrient medium. Alginate bead activity was significantly better than that with carrageenen beads (p<0.05). In grape must carrageenan beads disintegrated 10 times faster than alginate beads.
