The objective of this work was to study the resistance and removal capacity of heavy metals by the fungus Aspergillus niger. We analyzed the resistance to some heavy metals by dry weight and plate: the fungus grew in 2000 ppm of zinc, lead, and mercury, 1200 and 1000 ppm of arsenic (III) and (VI), 800 ppm of fluor and cobalt, and least in cadmium (400 ppm). With respect to their potential of removal of heavy metals, this removal was achieved for zinc (100%), mercury (83.2%), fluor (83%), cobalt (71.4%), fairly silver (48%), and copper (37%). The ideal conditions for the removal of 100 mg/L of the heavy metals were 28°C, pH between 4.0 and 5.5, 100 ppm of heavy metal, and 1 g of fungal biomass.

抗性真菌菌株黑曲霉对不同重金属的生物去除。

这项工作的目的是研究黑曲霉真菌对重金属的抗性和去除能力。我们通过干重和平板分析了对某些重金属的抵抗力：真菌在2000 ppm的锌，铅和汞中生长，在1200和1000 ppm的砷（III）和（VI）中生长，在800 ppm的氟和钴中生长，至少含镉（400 ppm）。就其去除重金属的潜力而言，锌（100％），汞（83.2％），氟（83％），钴（71.4％），相当的银（48％）和铜（ 37％）。去除100 mg / L重金属的理想条件是28°C，pH在4.0到5.5之间，100 ppm重金属和1 g真菌生物质。
