Enhanced Degradation of Phenanthrene by Soil Bioelectrochemical Systems: Synergistic Interaction between Humic Acids and Microorganisms

Abstract

AbstractPolycyclic aromatic hydrocarbons (PAHs) pose a persistent threat to soil ecosystems due to their recalcitrant nature and widespread distribution. This study investigates the role of humic acids (HAs) in enhancing phenanthrene (PHE) degradation and ...Schematic representation of the soil bioelectrochemical system (SBS) for PAH degradation. Humic acids (HAs) mediate electron transfer between microorganisms and the anode, facilitating the breakdown of phenanthrene in contaminated soil.
