摘要

Typical industrial logs of Radiata pine were treated with white rot fungi: Pleurotus sp. The treatment was separatedrnfrom another group considered as a control group. The treatment had three development periods for the fungal actionrnand the mean moisture level of logs was 80%. During the trial, and in order to know the evolution of chemicalrncomposition of the wood, classic determinations were made for lignin, cellulose, hemicellulose and extractants. As arnresponse of this treatment, the following characteristics and properties were evaluated: yield, Kappa index and viscosity.rnBased on chemical characterization, it was found that for Radiata pine, Pleurotus sp has an effective delignificationrnpower and with more residual hemicellulose. For biopulp from treated logs, the viscosity was a little higher than for therncontrol samples. In biopulps, for higher yields, the Kappa index is lower, and that means that bleaching could be lessrnintensive and contamination indexes decrease.
