摘要: Abstract The aim of this work was to test the growth response some selected species toxic metal vanadium, chosen among those isolated from contaminated agricultural soils (organochlorines, potentially elements) in “ Valle Latina ” (Lazio, Italy). This area contains high levels elements due both human activities and presence volcanic rocks (pyroclastic deposits). In particular, vanadium exceed threshold values established by Italian legislation. soil fungal community found be rich we tested responses six saprotrophic fungi ( Aspergillus terreus , Cladosporium cladosporioides Clonostachys rosea Paecilomyces lilacinus Penicillum citrinum Rhizopus arrhizus ). Culture medium (MEA) amended with ammonium vanadate at concentrations 1, 2, 3 6 mM. Results were based on measurements, tolerance index (TI), scanning electron microscopy (SEM), energy dispersion X-ray microanalysis (EDXA) concentration biomass determined means inductively coupled plasma mass spectrometry (ICP-MS). revealed a for all up Tolerance natural might key factor underlying their anthropogenic contamination.
