Energy Efficiency and Productivity Enhancement of Microbial Electrosynthesis of Acetate [PDF]

Frontiers in Microbiology, 2017
It was hypothesized that a lack of acetogenic biomass (biocatalyst) at the cathode of a microbial electrosynthesis system, due to electron and nutrient limitations, has prevented further improvement in acetate productivity and efficiency.

Microbial Electrosynthesis: Opportunities for Microbial Pure Cultures

Trends in Biotechnology
Microbial electrosynthesis (MES) is an emerging technology that couples renewable electricity to microbial production processes. Although advances in MES performance have been driven largely by microbial mixed cultures, we see a great limitation in the diversity, and hence value, of products that can be achieved in undefined mixed cultures. By contrast,

Simplifying Microbial Electrosynthesis Reactor Design [PDF]

Frontiers in Microbiology, 2015
Microbial electrosynthesis, an artificial form of photosynthesis, can efficiently convert carbon dioxide into organic commodities; however, this process has only previously been demonstrated in reactors that have features likely to be a barrier to scale ...

H2 mediated mixed culture microbial electrosynthesis for high titer acetate production from CO2 [PDF]

Environmental Science and Ecotechnology
Microbial electrosynthesis (MES) converts CO2 into value-added products such as volatile fatty acids (VFAs) with minimal energy use, but low production titer has limited scale-up and commercialization. Mediated electron transfer via H2 on the MES cathode

Mo2C-induced hydrogen production enhances microbial electrosynthesis of acetate from CO2 reduction [PDF]

Biotechnology for Biofuels, 2019
Background Microbial electrosynthesis (MES) is a biocathode-driven process, in which electroautotrophic microorganisms can directly uptake electrons or indirectly via H2 from the cathode as energy sources and CO2 as only carbon source to produce ...

Single-chamber microbial electrosynthesis reactor for nitrate reduction from waters with a low-electron donors’ concentration: from design and set-up to the optimal operating potential

Frontiers in Environmental Science, 2022
Microbial electrosynthesis is a promising solution for removing nitrate from water with a low concentration of electron donors. Three single-chamber microbial electrosynthesis reactors were constructed and operated for almost 2 years.

Cathodic biofilms – A prerequisite for microbial electrosynthesis

Bioresource Technology, 2022
Cathodic biofilms have an important role in CO2 bio-reduction to carboxylic acids and biofuels in microbial electrosynthesis (MES) cells. However, robust and resilient electroactive biofilms for an efficient CO2 conversion are difficult to achieve. In this review, the fundamentals of cathodic biofilm formation, including energy conservation, electron ...
