Biotechnological production of xylitol from lignocellulosic materials has been extensively investigated in the literature over the last decade, due to the importance of the utilization of the sewastes and the possibility of producing valueadded products[4,14,37]. Fig. 3 compares the results obtained in the batch production of xylitol from CABH with other wastes, emphasizing that the hemicellulose composition of each residue is diverse and may lead to different concentrations of ferment able sugars, and it was observed that the results obtained regarding xylitol production were higher than some showed in literature.
