Summary
This mini-review examines nano-enhanced microbial remediation as a green strategy for remediating soil contaminated with polycyclic aromatic hydrocarbons (PAHs). The authors synthesise recent evidence on how integration of nanomaterials with microorganisms can boost biodegradation efficacy, explore the mechanisms underpinning nanoparticle–microbe interactions in PAH remediation, and discuss future prospects for deployment in realistic environments. The work positions nanotechnology-assisted bioremediation as a viable approach to address soil pollution from industrial and transport sources.
UK applicability
The review's findings on nano-enhanced microbial remediation may be relevant to UK contaminated land remediation practice, particularly for historically industrialised sites with PAH contamination from coal, coke, or aluminium production. However, the applicability depends on the regulatory acceptance of nanomaterial deployment in UK soil remediation and the practical feasibility of scaling laboratory methods to field conditions.
Key measures
Mechanisms of nanoparticle-microbe interaction; efficacy of nano-enhanced bioremediation for PAH degradation; roles of various nanomaterials as remediation catalysts
Outcomes reported
The paper reviews the mechanisms by which nanomaterials enhance microbial degradation of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil. It synthesises evidence on nanoparticle–microbe interactions and discusses the prospective application of nano-enhanced microbial remediation in realistic field environments.
