| Minimidochium parvum LPSC # 548, a fungus isolated from litter floating on waters of Río Santiago (Provincia de Buenos Aires, Argentina) polluted with industrial effluents and crude-oil, was grown as a shaking culture on a C-limited medium to evaluate its ability to produce extracellular laccase. The effect of anthracene, CuSO4 · 5H2O, ethanol, guaiacol, humic acids, Kraft lignin, MnSO4· H2O, Tween 20 and veratryl alcohol on its growth and extracellular laccase activity levels was also analyzed. The cultures grown on basal medium produced maximum biomass (over 420 mg/100 ml) and maximum extracellular laccase activity (351.7 ±53.3 pkat/ml) after 5 days of incubation. Among the different factors tested, only the humic acids at 0.1 % (w/v) were found to... |

| Southern Hemisphere peatlands store substantial amounts of soil carbon. Despite their importance in the global carbon cycle, little is known about decomposition processes and the associated fungal diversity. The present study describes the composition of fungal assemblage in two depths from a cushion peatland of predominating Astelia (Asteliaceae) and Donatia (Donatiaceae) species in Moat, Tierra del Fuego. From 48 samples processed, we obtained 338 isolates. Using different culturing methodologies, through direct and microscopic observation and using molecular methods we identified 38 fungal species and 18 genera of Ascomycetes and Zygomycetes. Isolates belonging to Ascomycetes were the most abundant, with dominance of Penicillium and Trichoderma. We... |
