Experimental analysis demonstrates increased methane production at the cathode, highlighting microbial interactions with voltage variations.
Key Points
Methane production and concentration significantly increased in the cathode reactor, suggesting favorable conditions for hydrogenotrophic methanogens.
The anode environment reduced methane production while promoting organic acid generation through specific microbial species like Clostridium sensu stricto 1.
Analysis utilized separate reactors for anode and cathode, applying a constant voltage of 0.7 V to explore microbial responses.
These findings underline the potential of microbial electrochemical technology in enhancing methane fermentation through microbial ecology adjustments.
