Abstract. This study was conducted to evaluate the performance of free- and immobilized- cell systems in xylitol production process using Candida guilliermondii as the biocatalyst and a hemicellulosic hydrolysate derived from the hydrolysis of oat hull biomass as the medium. Both biotransformation performance and cell regeneration were greatly dependent on oxygen mass transfer coefficient (kLa). However, the process using immobilized biocatalyst demonstrated to be more flexible to the level of aeration rate. Application of the bio-based composite as the cell support in xylitol bioconversion process was examined and the results indicated that the composition of the support could be effective on the xylitol yield and productivity in repeated batch bioconversion process.
