Abstract: The effect of overall oxygen mass transfer coefficient ( k L a ) on the conversion of xylose to xylitol by Candida guilliermondii FTI 20037 was investigated in batch experiments. Rice straw hemicellulose hydrolysate obtained by acid hydrolysis was employed as a xylose-rich medium. The results showed that this bioconversion strongly depended on the aeration rate. The maximum volumetric productivity (0.52 g/l h −1 ) and the highest xylitol yield (0.73 g/g) were achieved at an overall oxygen mass transfer coefficient of 15 h −1 . Under these conditions 80% efficiency in relation to theoretical yield was attained.
