Abstract

The kinetic behaviour of the yeast Candida guilliermondii FTI 20037 was evaluated on a bench bioreactor using rice straw hydrolysate as a substrate. The maximum xylitol concentration (45.4gl−1) was attained after 45h of fermentation, which corresponded to a xylitol volumetric productivity of 1.01gl−1h−1. This value was improved in about 90% when compared to the results attained with aerated flasks (0.54gl−1h−1). The kinetic results obtained in the present work reinforce the idea that rice straw hydrolysate constitutes an effective xylose source for xylitol production.
