Postdoc Positions in Projects on Bioprocess and Metabolic Engineering with Anaerobic Gas-Fermenting Microbes

The research group of Environmental Biotechnology in the Center for Applied Geosciences at the University of Tübingen ( is looking for two excellent postdoctoral researchers to support our international, interdisciplinary, and dynamic team of environmental/biological engineers, microbiologists, biotechnologists, and molecular biologists.

The research in the Environmental Biotechnology group focuses on the recovery of carbon from diverse waste streams by open, mixed, and pure microbial cultures. Examples of utilized platforms are: 1) syngas fermentation to recover carbon from industrial waste gases; 2) chain elongation of ethanol and acetate or lactate to medium-chain carboxylic acids; 3) storage of electric power with microbial systems; and 4) microbial electrochemistry to study extracellular electron transfer in soils. We apply methods from bioreactor design and operation (lab- and pilot-scale), genetic engineering, and systems biology to next generation sequencing, proteomics, and sequence analysis of reactor microbiomes.

Activities and responsibilities

Qualified candidates have a doctoral degree in (micro)biology, biotechnology, biological engineering or related fields. The two available positions are part of BMBF-funded collaborative projects.

The first project has a main focus on bioreactor processing with acetogenic bacteria. The ideal candidate has experience on bioreactor systems with microbes, such as acetogenic bacteria under anaerobic conditions. Furthermore, knowledge on systems biology, such as proteomics and metabolomics is welcomed. The candidate will lead the design, building, and operation of bioreactors, evaluate fermentation parameters with bacterial strains in these systems, and collect and analyse omics data.

The second project focuses on genetic engineering of methanogenic archaea. The ideal candidate has experience with genetic modification and/or synthetic biology, and optimally with bioreactor systems. A real plus would be when the candidate had already worked genetically with “non-classical” microbes such as methanogenic archaea, acetogenic bacteria, actinomycetes, or (hyper)thermophiles. The candidate will work on developing genetic tools for methanogenic archaea, and will lead the design, building, and operation of bioreactors.

Qualification profile

The successful candidates are expected to supervise international PhD students, as well as bachelor and master students. Furthermore, they will closely interact with collaboration partners within the BMBF consortia. Therefore, very good English language skills are necessary. German language skills are helpful but not a requirement. Other requirements include the ability to do work independently and in a team, excellent management and communication skills, and a high motivation. Candidates will have the opportunity to present their results in international journals and conferences.

We offer

The positions are intended to be filled as soon as possible. The contracts are for 2 years and the employment will be arranged by the administration of the University of Tübingen (salary TVL E13, 100%). The University of Tübingen is seeking to increase the proportion of women in science and teaching, and therefore is asking qualified women to apply. Disabled persons will be preferred in case of equal qualification.

Send application to

Applications (in English) as one single pdf document including cover letter, CV, overview of techniques and methods used in the past, transcripts and diplomas, and contact address of two referees should be sent by email to Applications will be accepted until the positions are filled.
