AB [EN] The treatment of pig manure is a major environmental issue, and photobioreactors contain-ing consortia of microalgae and bacteria have proven to be a promising and sustainable treatmentalternative. This work studies the effect of Cu, Zn and As, three toxic elements frequently present inpiggery wastewater, on the performance and microbiome of photobioreactors. After dopage withZn (100 mg/L), Cu (100 mg/L), and As (500 μg/L), the high biomass uptake of Zn (69–81%) andCu (81–83%) decreased the carbon removal in the photobioreactors, inhibited the growth of Chlorellasp., and affected heterotrophic bacterial populations. The biomass As uptake result was low (19%)and actually promoted microalgae growth. The presence of Cu and As decreased nitrogen removal,reducing the abundance of denitrifying bacterial populations. The results showed that metal(loid)ssignificantly affected 24 bacterial genera and that they did not recover after exposure. Therefore,this study makes an important contribution on the impact of the presence of metal(loid)s in piggerywastewater that compromises the overall performance of PBRs, and so, the environmental and healthimpact of treated effluents
