PHENOLOXIDASES AND HYDROLASES FROM PYCNOPORUS-SANGUINEUS (UEC-2050 STRAIN) - APPLICATIONS

The basidiomycete, Pycnoporus sanguineus, possess lignin peroxidase, Mn-peroxidase, phenoloxidases, xylanase and beta-glucosidase activities when grown on malt extract. A large induction, mainly in laccase activity with malt extract/E1 effluent (46 U l-1), malt extract (100 U l-1) and malt extract/Eucalyptus grandis wood (61 U l-1) as carbon sources was found. The phenoloxidase capacity along with the presence of beta-glucosidase P. sanguineus led us investigate its use in effluent treatment. This fungus was efficient not only in chromophore group transformations but also in the reduction of phenols, biochemical and chemical oxygen demands, and toxicity.29321922
