For the utilization of polysaccharides from Pinus pinaster bark, both untreated and NaOH-treated samples were delignified to different stages using NaClO/sub 2/ and submitted to enzyme hydrolysis with Trichoderma reesei cellulase and Aspergillus niger beta-glucosidase. In the best conditions samples treated with 1% NaOH for 15 minutes and NaClO/sub 2/ for 7 hours the conversion of polysaccharides into sugars accounts for the 75% of the potential yield, and the glucose obtained amounts to 87% of the theoretical value. 37 references.
