Microbial electrogenesis – i.e. the generation of electricity from organic compounds in wastewater or marine sediments, and microbial electrosynthesis – i.e. the electrotrophic storage of electric current in organic molecules (e.g. from CO2), are two main applications of microbial electrochemical technologies. In both cases, the efficiency of the bioelectrochemical material and energy conversion depends strongly on the nature and the rate of electron transfer between microorganism and electrode. In this electron transfer, sulphur compounds can play an essential role, including intentionally as electron transfer mediators, but also (undesirably) in the formation of passivating surface layers. The main focus of this doctoral project is to improve the understanding of the role of sulphur compounds in extracellular electron transfer and thus to tailor bioelectrochemical processes.
What are your tasks?
The advertised position will be dedicated to a systematic experimental elucidation of the influence and reaction mechanisms of sulphur and sulphur compounds on the extracellular electron transfer in bioelectrochemical systems. The focus will be on the application of electrochemical methods in combination with microbial work.
