In the studied region, treatments with native and adapted microbial consortia were implemented, using seawater in the latter. Over 14 days, analyses of cell count, pH, and oxidation-reduction potential (ORP) were performed, showing an increase in microbial biomass and changes in the medium conditions, indicating a positive impact of the microorganisms on the sustainable recovery of copper. Atomic absorption analysis of the copper content revealed a significant increase at the end of the treatments, reaching 4.42% for the native microbial consortium (NMC) and 4.61% for the adapted microbial consortium (AMC), compared to the initial sample's 2.19%. The final results revealed significant species diversity, with Cutibacterium namnetense, Staphylococcus caprae , and Pelomonas aquatica predominating. This would indicate a positive impact of microbial consortia on sustainable copper recovery, and the microbial diversity suggests that the presence of the identified species could correspond to a signal of natural recovery of the environment, through a possible ecological succession over time. This would be an adaptation to address associated environmental challenges, and it would also highlight the importance of long-term strategies in the bioremediation of affected mining areas.
