Traditional anaerobic digestion (AD) technology continues to have severe limitations in terms of complicated substrate degradation efficiency and methane production. This study optimizes the AD system using corn straw cattle manure as substrates by introducing an exogenous N-Hexanoyl-L-Homoserine lactone (C6-HSL) signaling molecule concert with applied external voltage 0.8 V, systematically investigating its impact on methanogenic performance microbial community dynamics. The results show that combined regulation significantly increased production (by 29.74%) utilization rate 74.73%) while preventing acid inhibition ammonia nitrogen inhibition. Mechanistic analysis revealed enhanced system’s electrocatalytic activity, C6-HSL further facilitated electron transfer biofilm electrode. notably enriched hydrogenotrophic methanogens (with Methanobacterium predominating cathode Methanobrevibacter digestate), establishing a stable metabolic cooperative network both electrode digestate, optimizing methanogenesis pathway, enhancing synergistic effects among communities robustness. uncovers enhancement mechanism voltage, providing new technological pathways theoretical support for efficient conversion low-quality biomass resources clean energy.
