Tolerance to heavy metals in filamentous fungi isolated ...

2017-10-1 · The soils of the mining area had high concentrations of heavy metals. • A diversity of filamentous fungi was pinpointed. • Among the fungi isolated from these soils, Trichoderma harzianum was the most tolerant to all of the metals tested. Acremonium persicinum and Penicillium simplicissimum had the highest biosorption capacity of heavy metals.
