Coriolus versicolor f. antarcticus BAFC 266, Pycnoporus sanguineus BAFC 2126 and Phlebia brevispora BAFC 633 showed the highest phenoloxidase activity. Ganoderma applanatum strain E, P. sanguineus BAFC 2126 and P. brevispora BAFC 633 revealed marked laccase and peroxidase activity. C . versicolor f. antarcticus, G. applanatum (strain A) and Trametes villosa , gave high positive reactions with 2,6-dimethoxyphenol oxidation at the lowest tested pH. C. versicolor f. antarcticus , G. applanatum strains D and F, T. elegans BAFC 2127and T. villosa , showed the highest manganese peroxidase activity. C . versicolor f. antarcticus also produced the highest lignin peroxidase activity. Tyrosinase activity was mostly evident in G. applanatum strains (D and F) and Phanerochaete chrysosporium HHB 11741. Kraft liquor decolorization results were variable and depended on the fungus and the liquor concentration. Some fungi with moderate ligninolytic activity showed high decolorization rates (e.g. Pleurotus sajor-caju and Steccherinium sp. BAFC 1171) indicating the significance of additional approach to evaluate a potential biotechnological application. 2015 artículo científico 0120-548X https://www.redalyc.org/articulo.oa?id=319033067006 en http://www.redalyc.org/revista.oa?id=3190 Acta Biológica Colombiana application/pdf Universidad Nacional de Colombia Acta Biológica Colombiana (Colombia) Num.1 Vol.20 |
