Synergistic enhancement of anaerobic acidogenic fermentation in food waste: Role of extracellular polymeric substances and trace elements

Key Points

• The enhancement of anaerobic acidogenic fermentation is significantly influenced by extracellular polymeric substances—key in biomass degradation.
• Increased trace element availability leads to improved metabolic pathways during fermentation, enhancing overall efficiency and yield.
• Assessment using a combination of laboratory-scale experiments and biochemical analyses confirms the synergistic effects on fermentation rates.
• These findings highlight the potential for optimizing food waste management strategies through targeted enhancement interventions.
