| Palabra clave: | Isolation Fungi Heavy Metals Removal Lead (II) |
| Sumario: | Recently, has been studied the isolation and resistance to heavy metals of microorganisms, and his capacity of removal of different heavy metals in wastewater, such bacteria, yeast and fungi. Therefore, in this work, we isolate different fungal and yeast, which grow in presence of 200 ppm of lead (II), and we determined the tolerance to this metal by plate assays. Fungi found most frequently of wastewater were Penicillium sp., (44.5%), Trichoderma sp., (16.7%), and Alternaria sp., (8.3%) and from sludge were obtained Penicillium sp., (57.1%), and the yeast Candida albicans (42.8%). All species of isolated fungi and yeast were resistant to metal in the range of 500 to 2000 ppm. In addition, they have good capacity of removal this metal in solution: Mucor sp., (81%), Paecilomyces sp., I (66%), Penicillium sp., I, II, III, and IV (62%, 61%, 58%, and 55%). It was concluded that this fungi and yeast, could be used for decontamination of aquatic habitats polluted with lead (II). |
