Postdoctoral Researcher Position @ TU Braunschweig: Energy storage in electrotrophic-electrogenic biofilms.

Microbial electrogenesis, i.e., the production of electricity from organic compounds such as those found in wastes or marine sediments – and microbial electrosynthesis – the electrotrophic storage of electricity into organic energy storage molecules, are two prime application goals for microbial electrochemical technologies. Recent findings illustrate the possibility of combining electrotrophy and electrogenesis in one, switchable electrode-grown biofilm. This opportunity opens new ways to combine bioelectrochemical energy storage and power generation in a single device.
What are the mechanisms of the underlying metabolic processes, and how is the electrotrophic and electrogenic metabolism coupled with the extracellular electron transfer that connects cellular processes with the electrode? Single investigation methods, such as voltammetry or spectroscopy alone, will not allow achieve sufficient information depth. In collaboration with the Naval Research Laboratory in Washington, DC – and by using sophisticated in operando techniques, such as differential electrochemical mass spectrometry – this research project aims to study the mechanisms of such switchable biofilms.

Applications should be sent by e-mail (keyword “ONR-Project”) to Uwe Schröder (uwe.schroeder(at), and must contain the following documents.

– Motivation Letter including contact information for two references
– Curriculum Vitae including complete address, phone number, email address, educational background, language skills, and work experience-

Electrobioremediation of sediments contaminated by aromatic halogenated compounds and enrichment of dehalogenating microbial cultures

The research activities of this fellowship will be carried out in the frame of the H2020 research project Electra “Electricity driven Low Energy and Chemical input Technology foR Accelerated bioremediation”.

The research project aims at the development of an innovative process for the electrobioremediation of sediments contaminated by polyhalogenated organic pollutants. The process is based on the use of polarized electrodes deployed in the sediment able to promote the establishment of reducing and oxidative redox conditions and to provide the anaerobic and aerobic dechlorinating microorganisms with electron donors and acceptors, either directly or indirectly through water electrolysis. This approach can represent a clean and efficient method to stimulate and control the activity of dechlorinating bacteria in contaminated environments, as it avoids the supplementation of chemicals to the contaminated matrix, and may allow to increase the selectivity and control of the process. In particular, the research activity will aim at the development of a bioelectrochemical process in which the reductive dehalogenation and oxidative degradation processes will be stimulated sequentially within the matrix in order to promote the complete degradation of the pollutant.

Research plan

The research activity will consist in:

  • the set-up of H-type bioelectrochemical cells with contaminated sediment and the conduction of the process under varying operational conditions;
  • the evaluation of the system performances through: (i) the monitoring of target pollutants and their dechlorination/biodegradation products, (ii) the monitoring of the physico-chemical parameters of the matrix, (iii) mass and energy balances, (iv) the monitoring of the composition and dynamics of the microbial community;
  • the enrichment and isolation from the contaminated sediment of dehalogenating microbial communities and their characterization in terms of composition and biodegradative abilities towards different organohalogenated pollutants;
  • the selection of the best operational parameters and the validation of the process at mesocosm scale.

As regards the training aspects, the research fellow will have the opportunity to interact, in a highly interdisciplinary environment, with researchers from different disciplines who will offer the opportunity to expand their scientific and cultural background.
