Decolorization of Kraft liquor effluents and biochemical characterization of laccases from Phlebia brevispora BAFC 633
Fonseca, María Isabel; Fariña, Julia Ines; Sadañoski, Marcela Alejandra; D'Errico, Roger; Villalba, Laura Lidia; Zapata, Pedro Darío (Elsevier, 2015-10-01)In this work we evaluated the decolorization ability of fungus identified as Phlebia brevispora BAFC 633 on Kraft liquor effluents and we looked at the biochemical characterization of two novel laccases from the fungus. ... -
Effect of wood flour as carbon source on cellulases and xylanases production by white-rot-fungi native from Misiones
Rodríguez, María Daniela; Barchuk, Mónica Lucrecia; Fonseca, María Isabel; Zapata, Pedro Darío; Villalba, Laura Lidia (Council for Innovative Research, 2015-11-10)There is a need to explore lignocellulosic materials to select an adequate substrate for lignocellulolytic enzyme production. Utilization of some residues provides an opportunity to produce high yields of lignocellulolytic ... -
Evaluation of new xylanolytic-producing isolates of Aspergillus from Misiones subtropical rainforest using sugarcane bagasse
Díaz, Gabriela Verónica; Zapata, Pedro Darío; Villalba, Laura Lidia; Fonseca, María Isabel (Taylor & Francis, 2019-06-01)Xylanases hydrolyse efficiently the xylan component of hemicelluloses into single xylose monomers. Hence, these enzymes are suitable to be applied in the bioconversion of lignocellulosic wastes such as sugarcane bagasse ... -
Mycoremediation of high concentrations of polychlorinated biphenyls with Pleurotus sajor-caju LBM 105 as an effective and cheap treatment
