Abstract: The coal mining activity is characterized by the generation of large amount of by-products. One of them is pyrite, which tends to acidify the water, solubilizing heavy metals. As a consequence the environment becomes acid and rich in heavy metals, selecting microorganisms able to survive in this condition, which are of great interest as bioremediation agents. This work describes the isolation and characterization of microorganisms from a coal mining area in Santa Catarina. These microorganisms comprised bacter… Show more

“…Fungi can occur in the soil or in symbiosis with some plants that are capable of growing in such unfavorable conditions (Castro-Silva et al, 2003;Fujii and Fukunaga, 2008;Gibson and Mitchell, 2007). Our research confirms these observations.…”

“…Despite the fact that many metals, including Cu, Zn, Mn, and Co, are essential for microbial growth at low concentrations, many others have no essential biological function. For instance, As, Cd, Pb, Sn, and Cr are extremely toxic, even at low concentrations 3. All of these ions can exhibit varying degrees of toxicity toward living cells, because they damage molecules through their ability to interact with the thiol groups of proteins, which blocks and inactivates their functions.…”
