Summary
This narrative review appraises the application of microalgae-based systems for the remediation of refractory organic pollutants—recalcitrant compounds resistant to conventional treatment. The authors synthesise evidence on the biochemical mechanisms underpinning microalgal degradation capacity and identify operational factors that optimise treatment efficacy. The work positions microalgal biotechnology as a potentially cost-effective, photosynthetic remediation pathway with prospect of concurrent biomass valorisation.
Regional applicability
The findings are applicable to UK agro-industrial contexts where persistent organic contaminants (e.g. pesticide residues, xenobiotics) contaminate land and water; however, implementation would require localised feasibility assessment of microalgae cultivation and cost-effectiveness relative to existing remediation protocols under UK climatic and regulatory conditions.
Key measures
Pollutant degradation rates, microalgal enzymatic pathways, biomass yield, operational parameters (light, temperature, nutrient conditions)
Outcomes reported
The review synthesises evidence on microalgal capacity to degrade refractory organic pollutants through metabolic and enzymatic pathways. Examined operational parameters and conditions that enhance bioremediation efficacy alongside potential co-products.
