Reducing Oxygen Stress and Improving Hydrogen Availability Boosts Microbial Electrosynthesis by Clostridium ljungdahlii. [PDF]
ChemSusChemMicrobial electrosynthesis (MES) from CO2 by acetogens enables the production of value‐added chemicals. However, its current limitations include O2 stress and insufficient H2 availability. Using Clostridium ljungdahlii as a model in 1‐L electrobioreactors providing high process control, MES is boosted to unprecedent acetate concentrations and rates ...
