Fermentative processes for the upcycling of xylose to xylitol by immobilized cells of Pichia fermentans WC1507.

ABSTRACT: Xylitol is a pentose-polyol widely applied in the food and pharmaceutical industry. It can be produced from lignocellulosic biomass, valorizing second-generation feedstocks. Biotechnological production of xylitol requires scalable solutions suitable for industrial scale processes. Immobilized-cells systems offer numerous advantages. Although fungal pellet carriers have gained attention, their application in xylitol production remains unexplored. In this study, the yeast strain P. fermentans WC 1507 was employed for xylitol production. The optimal conditions were observed with free-cell cultures at pH above 3.5, low oxygenation, and medium containing (NH₄)₂SO₄ and yeast extract as nitrogen sources (xylitol titer 79.4 g/L, Y_P/S 66.3%, and vo
