Resumen del seminario:

Acid mine drainage (AMD) occurs when waste from the extraction and processing of sulfide ore comes into contact with oxygenated water. AMD contains high concentrations of sulfate, metals and metalloids including arsenic. AMD is a unique ecological niche for acid- and toxic-metals-adapted microorganisms. Because microbial metabolic activities influence the biogeochemical cycles of elements, they play a crucial role in AMD functioning. The interest in the study of AMD has exponentially increased during the last decade. Particularly, the characterisation of microbial communities using 16S rRNA high-throughput sequencing and community genomic methodologies has provided significant advances in our understanding of microbial ecology in acidic extreme environments. AMD microbial ecology, the dynamics of microbial diversity and community functions will be presented, with a focus on the Carnoulès AMD (France), the most arsenic contaminated AMD in the world.
