abstract

• Lead is a heavy metal that causes toxic effects on the gastrointestinal tract, renal system, central and peripheral nervous system, as well as interference with enzymatic systems involved in the synthesis of the heme group, so it is important to try to eliminate it from the different contaminated ecological niches. There are reports that mention that fungi have heavy metal uptake abilities, due to some components of their cell wall. In this work, the biosorption of lead by 18 fungal biomasses of fungi isolated from soils of a gas station in the industrial zone of San Luis Potosí, S.L.P., México was studied, finding that the biomasses of Penicillium sp-1, Mucor sp., Paecilomyces sp-1 and Penicillium sp-2, were the most efficient to remove the metal (determined spectrophotometrically at 510 nm using dithizone as a complexing agent), with the following removal percentages, 63%25, 63%25, 60%25 and 59%25, respectively at a pH of 4.0, 28 °C and 24 h of incubation, 100 mg/L of lead (II), 100 rpm, and 1.0 g/100 mL of fungal biomass. This technology can provide faster and more reliable methods to optimize energy resources from biological sources. Too, we studied the capacity of removal of this metal by four fungal strains of Penicillium sp., isolated of the same place.
