Tolerance and biosorption capacity of ZnĀ²āŗ, PbĀ²āŗ, NiĀ³āŗ and CuĀ²āŗ by filamentous fungi (Trichoderma harzianum, T. aureoviride and T. virens)
Heavy metal pollution has become a serious environmental issue in the last few decades. There is a need to develop potential technology that can remove toxic heavy metals ions found in polluted environments. This study was undertaken to determine the resistance levels of different concentrations of heavy metals using filamentous fungi of Trichoderma aureoviride, T. harzianum, and T. virens. Based on the results, the T. virens strain T128 gave the highest tolerance ability for NiĀ³āŗ and PbĀ²āŗ in a 1200 mg/L concentration. The accumulation and uptake capacity was determined by the maximum removal of PbĀ²āŗ, CuĀ²āŗ, and NiĀ³āŗ by a T. harzianum in liquid medium when compared to other fungi. The metal removal occurred at a concentration of 500 mg/L and was 13.48 g/g for PbĀ²āŗ, 3.1254 g/g for CuĀ²āŗ and 0.8351 g/g for NiĀ³āŗ. For ZnĀ²āŗ, the highest tolerance and uptake capacity of metal was recorded at 3.1789 g/g by T. virens
