| ABSTRACT The purpose of this study was to demonstrate the in vitro free radical scavenging activity and antioxidant capacity in solid-state fermented wheat bran and its potential modulation of antioxidative molecular targets in chicken peripheral blood mononuclear cells (PBMC). After solid-state fermentation of wheat bran by white rot fungi for 12 d, the scavenging action of the fermented wheat bran extracts was 1, 1-diphenyl-2-picrylhydrazyl (DPPH), and the free radicals increased significantly, approximately 1.5-fold. Trolox equivalent antioxidant capacity of 1 mg/mL fermented wheat bran extracts was increased from 100 to 150 mM trolox antioxidant capacity after 12 d of fermentation. Moreover, the extracts exhibited 50% of the chelating capacity observed... |

| Abstract Oxidative enzymes secreted by white rot fungi can be applied in several technological processes within the paper industry, biofuel production and bioremediation. The discovery of native strains from the biodiverse Misiones (Argentina) forest can provide useful enzymes for biotechnological purposes. In this work, we evaluated the laccase and manganese peroxidase secretion abilities of four newly discovered strains of Trametes sp. that are native to Misiones. In addition, the copper response and optimal pH and temperature for laccase activity in culture supernatants were determined.The selected strains produced variable amounts of laccase and MnP; when Cu2+ was added, both enzymes were significantly increased. Zymograms showed that two isoenzymes... |

| Four white rot fungi (WRF) strains, Phanerochaete chrysosporium, Trametes versicolor, Coriolopsis polyzona and Pycnoporus coccineus, were tested for efficiency of treatment of Olive Oil mill wastewaters (OOMW) in relation with their cultivation mode, i.e. under the form of free mycelium, mycelium immobilized in alginate beads and solid state cultivation on Petri dishes. Study of biodegradation of phenolic compounds, chemical oxygen demand (COD) decrease and decolourisation of OOMW have shown that Coriolopsis polyzona and Pycnoporus coccineus degradation performances were apparently only slightly affected by the cell cultivation procedures experienced here. In contrast, Phanerochaete chrysosporium and Trametes versicolor showed respectively marked... |

| White-rot fungi have demonstrated a high capacity to degrade organic pollutants, including the insecticide lindane (y-HCH). The purpose of this study was to evalúate the degradative capacities of several white rot fungi species, Bjerkandera adusta, Irpex lacteus, Lentinus tigrinus, Phanerochaete chrysosporium, Phanerochaete sórdida, Phlebia radiata, Pleurotus eryngii, Poliporus cialatus, and Stereum hirsutum. Fungal tolerance to various concentrations of a-, (3-, y- and 8 isomers of hexachlorocyclohexane (HCH) was studied in both liquid and soil media samples. 8- and y-HCH isomers showed the highest inhibition of fungal growth of all HCH isomers. P. chrysosporium and B. adusta exhibited a high tolerance to HCH pollution. The 8- and y-HCH isomers were... |
