|Title:||DECAY OF PARKIA-OPPOSITIFOLIA IN AMAZONIA BY PYCNOPORUS-SANGUINEUS AND POTENTIAL USE FOR EFFLUENT DECOLORIZATION|
|Abstract:||Chemical characterization and scanning electron microscopy of decayed Parkia oppositifolia by Pycnoporus sanguineus demonstrated a first stage of non-selective wood decay followed by an increased rate of lignin degradation during the advanced stages. The inorganic contituents on Parkia with advanced decay exhibited 9 fold increase in ash content compared to sound wood. The ash had a black color, and was presumably manganese oxide. Ca-oxalate crystals were present in the parenchymal cells of decayed wood but not observed in cell of sound wood. The ligninase. Mn-peroxidase and beta-glucosidase activities present in P. sanguineus indicate a great potential for industrial use, specially in effluent treatment. In fact, this fungus was efficient in decolorization and decontamination of Kraft E1 and C1/E1 effluents.|
