Malate degradation by Schizosaccharomyces yeasts included in alginate beads
Résumé
Schizosaccharomyces yeasts can be used for deacidification of grape musts. To this aim, we studied malic acid degradation by yeasts included in double layer alginate beads in a bubble column reactor. Use of immobilized micro-organisms allowed a continuous process with high dilution rates giving a deacidification capacity of 0.032 g of malate/hour/dm3/g of beads. The pneumatic agitation was very convenient in this case.
