Implication

This experiment demonstrates improved acetate production in Clostridium ljungdahlii by addressing O2 stress and hydrogen availability, suggesting significant optimizations for future engineering.

Key Points

High acetate production rates were achieved by managing oxygen levels and hydrogen supply.
12.44 g L−1 of acetate concentration was recorded using optimized cathode and anode configurations.
Using a 1-L electrobioreactor demonstrates the potential for scaling microbial electrosynthesis effectively.
The findings indicate that current anaerobic MES systems still have considerable room for improvement and optimization.
