Polydopamine-coated photoautotrophic bacteria for improving extracellular electron transfer in living photovoltaics

Fabian Fischer, Ardemis Anoush Boghossian, Charlotte Elisabeth Marie Roullier, Melania Reggente, Mohammed Mouhib, Patricia Brandl, Hanxuan Wang

Living photovoltaics are microbial electrochemical devices that use whole cell–electrode interactions to convert solar energy to electricity. The bottleneck in these technologies is the limited electron transfer between the microbe and the electrode surfac ...

In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer

Fabian Fischer, Ardemis Anoush Boghossian, Melania Reggente

Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...

Modeling of Sustainable Base Production by Microbial Electrolysis Cell

Christos Comninellis, Fabian Fischer, Maxime Blatter, Marc Sugnaux

A predictive model for the microbial/electrochemical base formation from wastewater was established and compared to experimental conditions within a microbial electrolysis cell. A Na2SO4/K2SO4 anolyte showed that model prediction matched experimental resul ...

Scale-up of phosphate remobilization from sewage sludge in a microbial fuel cell

Christos Comninellis, Fabian Fischer, Géraldine Zufferey, Alain-François Grogg, Marc Sugnaux, Thomas Egli

Phosphate remobilization from digested sewage sludge containing iron phosphate was scaled-up in a microbial fuel cell (MFC). A 3 litre triple chambered MFC was constructed. This reactor was operated as a microbial fuel cell and later as a microbial electro ...
