Homoacetogenic Clostridium magnum WY-4 as a bio-stabilizing agent in anaerobic digestion
Anaerobic digestion is an important process for organic waste treatment and renewable energy production, but it is often limited by low microbial activity and process instability. This project investigates the effect of the homoacetogenic bacterium Clostridium magnum WY-4 as a novel bio-stabilizing agent in anaerobic sludge digestion. High-throughput 16S rRNA sequencing was used to evaluate changes in microbial community composition and signaling molecules in response to WY-4 supplementation. The study provides insight into how homoacetogens can enhance methane yield, stabilize volatile fatty acid metabolism, and improve the ecological regulation of anaerobic bioprocesses.
