Among the possible biotechnological alternatives to perform xylitol production, the Submerged Fermentation (SmF) method has widely been investigated ultimatelty, using different configurations. However, little is known on the use of the Solid-State Fermentation (SSF) to carry out such a bioprocess. Taking into account the well-known advantages of this mode of operation over the SmF, this study aims at evaluating the potential of Solid-State Fermentation (SSF) for this bioprocess. SSF runs have been done at 30ºC, under oxygen limited conditions, in polypropylene sachets, using sugarcane bagasse as inert support, commercial xylose as substrate and Candida guilliermondii as the fermenting yeast.
