Resumo: Previous tests using a growth medium and olive mill wastewater (OMWW) have shown that it supplies carbon and electron donors suitable for sulphate reducing bacteria (SRB). We assessed the co-treatment of acid mine drainage (AMD) and OMWW using SRB-enriched bioreactors and identified the most abundant bacterial populations present under optimized conditions. The process requires a neutralizing agent to create optimal pH conditions for successful removal of the AMD's main contaminants. Concentrations of SO42-, Al, Fe, Cu, Zn, and Mn decreased to below Portugal's maximum admissible values for irrigation waters, and all but Mn were reduced to less than Portugal's emission limit values (ELVs) for wastewater discharges. Phenol concentrations-the main pollutants in OMWW-dropped to values between 1/10 and 1/5 their initial concentrations in batch tests using mixtures of AMD and OMWW, and to 1/2 their initial concentrations in flow-through tests. The final total phenol concentrations were still above the ELV for wastewater discharges, but phenols are not regulated in irrigation waters, and OMWW is used by some producers to irrigate soils. Six main SRB groups were identified as likely having a fundamental role in the bioremediation process: the generaDesulfovibrio,Sulfurospirillum, andAcetobacterand the familiesSphingomonadaceae,Prevotellaceae, andDeferribacteraceae
