Coupling alternating current field with biostimulants enhances lignite biomethanation, with evidence consistent with extracellular electron transfer, electron bifurcation, and co-metabolism.

Anaerobic conversion of lignite to methane is hindered by its aromatic structure and phenolic toxicity. Applying an alternating-current (AC) electric field (1.0 Vrms/cm, 500 kHz) with biostimulants markedly enhanced methane production by stimulating…
