Abstract

This work deals with the biotechnological production of xylitol from xylose of hemicellulosic hydrolysates of sugarcane bagasse, eucalyptus, rice straw and wheat straw, by the yeast Candida guilliermondii FTI 20037. The hydrolysates were evaporated under vacuum in order to achieve a xylose concentration about 100 g/L and then treated with CaO until pH 7.0 and H3PO4 until pH 5.5, followed by activated charcoal (2.4 %). The fermentations of hydrolysates were carried out in 125 mL Erlenmeyer flasks, in shaker at 300 rpm, during 80 h. By the kinetic study it was possible to observe the behavior of the yeast under the different characteristics of hydrolysates and the consequences on the fermentation parameters.It was obtained a volumetric productivity of 0.50 g/Lh for the hydrolysate from sugarcane bagasse, 0.35 g/Lh for ricestraw, 0.34 g/Lh for eucalyptus and 0.24 g/Lh for wheat straw.
