Study on the diversity of anaerobic digestion microorganisms after ethanol pre-fermentation

Using ethanol pretreatment as an intervention method for inter-species electron transfer and different TS gradients as variables, this study explores the enhancement of anaerobic digestion reactors by ethanol pretreatment under different TS conditions and the effect of acid inhibition relief. The microbial population morphology and other related conditions are also explored. The study conducts batch experiments to select typical TS conditions for long-term operation to study the enhancement effect.
