Abstract

The objective of this work was study the resistance and removal capacity of heavy metals by the fungi Aspergillus niger. We analyzed the resistance to some heavy metals by dry weight and plate: the fungi it grows in 2000 ppm of zinc, lead, and mercury, 1200 and 1000ppm of arsenic (III) and (VI), 800ppm of fluor and cobalt and least in cadmium (400ppm). With respect to their potential of removal of heavy metals, this removal efficiently zinc, (100%), mercury (83.2%), fluor (83%), cobalt (71.4%), fairly silver (48%) and copper (37%). We determine the optimal characteristics for lead, mercury, cobalt and zinc removal in dry cells. The ideal conditions for the removal of 100mg/L of the heavy metals Cr (VI) were 28 °C, pH between 4.0-5.5, 100ppm of heavy metal, and 5g of fungal biomass.
