Abstract

The Osamu Utsumi mine of Brazilian nuclear industries (INB), located in the city of Caldas/MG, was the first uranium (U) mine in Brazil and was closed in 1995. Since then, it has been in the decommissioning phase with problems in rehabilitating areas with contamination caused by uranium mining activities. Currently the mine has high levels of uranium contamination. Bioremediation is an alternative technology for the remediation of sites contaminated with heavy metals. The potential of fungi for the biosorption of heavy metals from contaminated environments and great production of enzymes has been recognized, thus, the aim of the present project is to analyze the phosphate biomineralization by microorganisms and simulation of uranium remediation from tailings. The new methods developed and validated could be implemented in the research of Brazilian groups and also will provide significant knowledge about bioremediation in uranium mines. Other aspects considering fungi and uranium mine bioremediation can be investigated and also could be applied to the research. (AU)
