PhD position on electron conduction in cable bacteria

Cable bacteria are filamentous bacteria that can conduct electrons across centimetre-scale distances and thereby metabolize distantly located electron donors and acceptors in aquatic sediment. The DNRF Center for Electromicrobiology at Aarhus University is looking for a motivated and talented PhD student to investigate how cable bacteria and their electron conductors work, based on the numerous options and challenges that this exceptional scale of biological electron transport poses for experimental studies.

PhD position on genomic and ecophysiological diversity of cable bacteria

The DNRF Center for Electromicrobiology at the Department of Biology, Aarhus University is looking for a motivated and talented PhD student to work with cable bacteria. Cable bacteria are filamentous sulfide-oxidizing bacteria that conduct electrons across centimetre-scale distances in aquatic sediment. Most of the factors driving cable bacteria genetic divergence and evolution are currently unknown. The student will address the ecophysiology, taxonomic diversity, and evolution of cable bacteria using molecular approaches (metagenomics, amplicon sequencing, qPCR) as well as microcosm-scale experiments to profile the physiological characteristics of different cable bacteria strains or to perform competition experiments.

PhD position in the field of enzymatic electrosynthesis

We are looking for a talented student with a strong background in biochemistry to fill a four-year PhD post within the Academy of Finland Fellowship project “Novel biocatalysts for a sustainable bioeconomy – enzyme structures enabling carbon dioxide valorisation at electrodes”.

Project description
This project is inspired by the recent discovery of an archaeal enzyme complex, which catalyses the reduction of CO2 at submerged electrodes. Within this project, it will be attempted to determine the structure of this archaeal enzyme complex and a functionally related bacterial enzyme complex and use this information for the development of novel electrosynthetic enzymes. Thereby, this project explores the possibility to decrease anthropogenic CO2 emissions by replacing oil-based processes for chemicals production with more sustainable bioprocesses.

Job description
The PhD student will be primarily based at VTT’s Industrial Biotechnology and Food Solutions unit, which is located on the Otaniemi campus in Espoo. Additional national sites of research are the Biochemistry Department at Aalto University (Espoo) and the Biocenter Oulu and Faculty of Biochemistry and Molecular Medicine at the University of Oulu, where a part of the protein purification and structural data analysis and modelling will be performed. The student is expected to participate in international collaboration by conducting part of the research at our partner institutions Stanford University and University of Tokyo during periods of about six and two months, respectively.

Most experiments will be performed in anaerobic chambers and utilize Escherichia coli and Methanococcus maripaludis as protein production hosts. The main project objectives include genetic manipulation of these species as well as method development for the crystallization of the electrosynthetic enzyme complexes and their functional characterisation as catalysts in electrosynthetic systems.

VTT Offers
The project is supported by VTT’s excellent research facilities, a friendly work environment and an interdisciplinary network of highly skilled experts and research support staff. The hosting organisation is VTT Technical Research Centre of Finland (VTT), which is an impartial non-profit Research and Technology Organisation that uses its close ties to academia and industry to promote the application of science. The doctoral position is funded for four years and will be filled as soon as a suitable candidate has been found.

A successful applicant is expected to have an MSc degree or equivalent in a relevant field of science such as protein biochemistry, crystallography and protein design with the desire for lab-work. The candidate shall have demonstrable competence of common microbiology and molecular biology laboratory skills, such as culturing of microorganisms, gene cloning and enzyme assays. Competence in analysis of protein structural data is also desired.

Urgent Notice on the Postponement of the 5th Asia-Pacific International Society of Microbial Electrochemistry and Technology Conference

The 5th Asia-Pacific International Society of Microbial Electrochemistry and Technology Conference (5th AP-ISMET) hosted by the Harbin Institute of Technology, School of Environment was originally scheduled to be held on March 6-9, 2020, at Harbin Victories Hotel, Harbin, China. Preparations were completed and 300 participants were expected.

In accordance with the relevant national and provincial regulations for the control of the novel coronavirus (2019-nCoV) epidemic, the Harbin Institute of Technology has adopted a prevention policy stipulating that “All forums, formations, lectures, performances, competitions, admissions examinations, and other large collective activities will be cancelled” until further notice. According to this regulation, Harbin Institute of Technology, School of Environment has requested the postponement of the 5th AP-ISMET. The conference organizing committee will make the following notifications in order:

1. In its initial assessment, the organizing committee has decided to postpone the 5th AP-ISMET conference to a date to be determined in the middle of August 2020. The meeting topics and activities will remain unchanged.

2. For the participants who have completed registration and payment, all the conference activities registered for participation will be valid at the time of the conference and will continue to be implemented.

3. For delegates who have already paid their fees and are unable to attend the conference in August, the organizing committee will refund the registration fees after the August conference.

4. The 5th AP-ISMET special issue in Science of the Total Environment will continue to be implemented as originally planned.

5. Because of the postponement of the conference, abstracts submission deadline will be extended to May 30, 2020, and conference registration deadline will be extended to June 30, 2020.

We sincerely apologize for the inconvenience caused by the postponement of the 5th AP-ISMET conference. We express our heartfelt thanks for your understanding and look forward to the end of the epidemic.

Exploring natural and artificial biofilms of acetogenic bacteria to improve microbial electrosynthesis rates


Research area and project description:

Microbial electrosynthesis is a novel biotechnological process for the conversion of excess renewable electricity and CO2 into biofuels or other organic compounds. This process relies on acetogenic bacteria capable of reducing CO2 to organic compounds using electrons delivered by an electrode (cathode). One major problem limiting the rate of microbial electrosynthesis is the low number of bacterial cells that attach to a cathode. This Phd will investigate whether the production rate of microbial electrosynthesis can be improved by increasing the number of cells on the cathode.

The project will explore two different strategies to increase cell numbers on cathodes. First, natural biofilm formation will be stimulated by condition selection and adaptation. Second, artificial biofilms will be created by immobilizing cells in different polymeric matrices. These natural and artificial biofilms will allow to increase and control the cell numbers on cathodes and assess the effect of attached cell numbers on microbial electrosynthesis rates. Several state-of-the-art techniques, including confocal microscopy and microsensor measurements, will be applied to characterize the two type of biofilms.

Qualifications and specific competences:

We are looking for talented and enthusiastic applicants with a Master’s degree in Microbiology, Bioengineering, Biotechnology, or another discipline with a relevant specialisation. Practical experience with the cultivation of anaerobes, biofilms, cell immobilization, bioelectrochemical systems, etc. will be considered as a plus. Analytical and critical thinking are essential to pursuit a PhD. Further requirements are English fluency and being a team player.

Place of employment and place of work:

This project is a collaboration between the Microbial Electrosynthesis research group, headed by Assistant Professor Jo Philips (Engineering Department) and the Sensor research group of Assistant Professor Klaus Koren (Bioscience Department).

The place of work will be in at Section of Biological and Chemical Engineering, Department of Engineering, Hangøvej 2, 8200 Aarhus N, Denmark. Aarhus University is located in the vibrant city of Aarhus.
