Mine waters often contain selenate, which needs to be removed to avoid harmful human and environmental health impacts. This study evaluated the performance of a laboratory-scale inverse fluidised bed reactor (IFBR) for biological selenate reduction a

The role of fungi in the biogeochemical cycling of gold remains unclear. Here the authors show that fungi can initiate gold oxidation under supergene conditions, thereby impacting gold mobilisation and secondary deposit formation in terrestrial envir
