Bioremediation using microorganisms to remediate petroleum hydrocarbon contaminated soils is considered as a sustainable approach to cleaning polluted sites. One element of the sustainability is providing nutrients (biostimulation) for degrading microbial populations by using organic wastes such as animal manures rather than conventionally produced mineral fertilisers. Waste management practices are increasingly concerned with resource recovery considering organic wastes as being valuable resources in the context of a more circular economy. Greater attention should be given to the potential benefits of managing organic wastes in a symbiotic approach alongside bioremediation of contaminated soils. However, organic nutrients such as animal manures often contain antibiotic residues, resistant bacteria and genes for antimicrobial resistances. Co-selection pressures from pollutants such as heavy metals and hydrocarbons may lead to pre-existing adaptations in microbial communities living in contaminated soils. The potential risks to human health from increasing the diversity and abundance of antibiotic resistant strains arising from contaminated soils requires further investigation. This review examines some of the opportunities and barriers that exist for symbiosis between the management of organic wastes and bioremediation of hydrocarbon contaminated soils.
