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.

2-years Post-doc position in industry

We are offering a 2-years Post-doc position in industry. The project is funded by our start-up company Algaria through research grants. It is in collaboration with the University of Milan (Italy) and other research institutions. The project focuses on electroactive biochar (material developed by us) and on some applications in the field of microbial electrochemical technologies applied to the recycling of nutrients from agri-food chains. In particular, we have a patent for an ‘electroactive artificial soil’, combined with the cultivation of Spirulina, to recover nutrients from agri-food waste. Another application is in hydroponic agriculture (with a partner company). In Algaria, we are developing the application to TRL7 of this patent for the cultivation of spirulina. The project deals also with a TRL8-pilot for the extraction of phycocyanin (food coloring) from Spirulina, at our production plant near Cremona (Italy). We are looking for a highly-skilled research profile, to be responsible for the research project with the University of Milan and at the same time become responsible for the production and R&D of Algaria.

Fundamentals of energy storage in electrochemically active biofilms

The Institute of Environmental and Sustainable Chemistry, TU Braunschweig, Germany, is looking for an excellent Phd student to support our interdisciplinary research project “Fundamentals of canode biofilm electro-metabolism”.

Microbial electrogenesis – the electricity production from organic compounds such as those found in wastes or marine sediments – and microbial electrosynthesis – the reduction of CO2 into organic energy storage molecules, are two prime application goals for microbial electrochemical technologies. Recent findings by the team of Dr. Leonard Tender from the Naval Research Laboratory in Washington, DC illustrate the possibility of combining electrotrophy and electrogenesis in one, switchable electrode-grown biofilm denoted as canode biofilm (cathode/anode). The canode opens new ways to combine bioelectrochemical energy storage and power generation in a single device.

But 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. Only by combining these methods (so-called hyphenated techniques) to probe real-times changes in molecular signatures of the canode, as it switched for energy storage to power generation modes, can information down to molecular reaction mechanisms be gained. In this research project – which is carried out in collaboration with the group of Dr. Leonard Tender – we take a further step. We combine a set of state of the art hyphenated techniques in order to close this knowledge gap and acquire fundamental understanding on the thermodynamics, mechanisms and kinetics of the energy conversion and metabolism in canode biofilms.

The starting date is October 1, 2020. The employment will be arranged by the administration of the TU Braunschweig (salary TVL E13/50%, including health insurance, 3 years contract).

Applications: should be sent by e-mail to Uwe Schröder (uwe.schroeder@tu-braunschweig.de), 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
Copies of diploma and transcript of grades in original language and in English or German translation
Additional documents should be provided on request
All documents should be in PDF format, preferably in a single file. Personal data and documents relating to the application process will be stored electronically. Please note that application costs cannot be refunded.

PhD position “Design of a Bioelectrochemical Biogas Plant”

The Research Group Environmental Process Engineering at the University of Bremen (Germany) seeks candidates for a PhD position (36 months) in the field of designing a bioelectrochemical biogas plant. Candidates should hold a Master’s degree (or equivalent) in
Chemical & Environmental Engineering, Mechanical Engineering, Biotechnology (or related fields)

*Your tasks*
The underlying idea of this project is the integration of a microbial electrolysis cell into the biogas plant. At the MECs anode, organic acids are oxidized to carbon dioxide, releasing electrons. These electrons can in turn be used at the cathode to reduce protons to molecular hydrogen. By the electrochemical oxidation of organic acids at the anode, the acidification of the fermenter can be prevented while at the same time pure hydrogen is obtained, which can be further used e.g. to produce valuable chemicals. Your tasks include the characterization and development suitable electrode and membrane materials to construct the microbial electrolysis cell. Based on these materials, an MEC design suitable for integration into the biogas plant shall be developed, and implemented into a model biogas plant. Finally, the complete system will be extensively characterized and limited processes identified. Special regard shall be given to the prevention of hydrogenotrophic microbial growth at the cathode, which would reduce the hydrogen yield.

*Your profile*
We are looking for highly motivated individuals with excellent scientific record. Successful candidates must be good experimentators and possess strong communication skills. Ideally, the candidates have previous experience in the fields of (bio-)electrochemistry.

*What we offer*
The University of Bremen and its Center for Environmental Research and Sustainable Technology offer an excellent scientific environment for interdisciplinary research. The full-time position (salary level 100% E 13) is affiliated to the Research Group Environmental Process Engineering. Our interdisciplinary research is focused on fundamentals, materials, and processes for sustainable environmental engineering and biotechnology.
