PhD Position (m/f/x) on Electrode-driven Biochemical Synthesis using Pseudomonas putida

Balancing microbial redox metabolism using electrode decouples the carbon and electron fluxes for biochemical synthesis, and thus enables the high yield bioproduction process that naturally does not exist. Within the joint DFG SPP2240 project ePseudomonas together with Prof. Wittmann (iSbio, Saarland University, Germany), we aim to develop a universal tunable electro-fermentation platform using metabolically engineered Pseudomonas putida for the biosynthesis of high-value chemicals of industrial interests. To realize this ambitious goal, we are seeking an enthusiastic person to fill a PhD position funded by this project. The student will primarily focus on the fundamental and quantitative understanding of the Pseudomonas putida’s behaviors in the bioelectrochemical system (BES), using e.g. systems biology tools, and then rationally optimize the electro-fermentation process from the aspects of e.g. the process engineering and systems metabolic engineering.

Congratulations to both! Well done!

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)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.

The open position is to be filled as soon as possible. The employment will be arranged by the administration of the TU Braunschweig (salary TVL E13, including health insurance, 1.5 years contract).

PhD position in bioelectrochemical enrichment of metals

The University of Bremen is offering (under the condition of job release) at the earliest possible date:

Ph.D. position in bioelectrochemical enrichment of metals
Salary group 13 TV-L (75 %), 36 months

in an interdisciplinary project at the interface of microbiology, electrochemistry and material sciences. The motivation of this PhD project is the search for new technological approaches for the extraterrestrial fabrication of metal alloys under tough environmental constraints, in particular the limitation of utilizing mineral and energy resources available in situ on Mars or Moon. More specifically, the project aims at exploring bio-based possibilities to extract iron species from regolith and enrich them as purified iron compounds. These compounds are then used in steel-making processes based on non-conventional metallurgy. In this sub project, microbial electrochemical technologies such as microbial fuel cells (MFCs) and microbial electrolysis cells (MECs) will be used for enhanced production and selective recovery of metal ion species. Microbial communities developing in MFCs will be characterized using state-of-the-art tools such as high-throughput sequencing, metagenomics and metatranscriptomics.

Within the new research initiative in close collaboration with the Hochschule Bremen (HSB), Ph.D. students are supervised by a team of experienced scientists ranging from electrochemistry, material sciences to microbiology and biomimetics. Additional training and support are offered by international graduate Programmes within the MAPEX Center for Materials and Processes, the MarMic Graduate School and the Biomimetic-Innovation-Centre (HSB). These offers include expert as well as skills and methods courses, coaching, networking opportunities, and the opportunity to compete for internal funds. Ph.D. students have the opportunity to acquire expert knowledge in their field and a solid background across many disciplines involved in the interdisciplinary project.

Specific tasks will include:
1. Setting up and running novel microbial electrochemical enrichments
2. Characterization of metal ions and solid metal compounds by chemical and spectroscopic methods
3. Extraction and analysis of nucleic acids from bioreactor samples
4. Investigation and optimization of conversion efficiency and energy demands
5. Bioinformatic and statistical analysis of data
6. Opportunity for scientific qualification in the context of a PhD degree

Your profile:
• A completed MSc or diploma degree in Microbiology, Biochemistry, Electrochemistry, Material Sciences or a comparable program
• Interest in interdisciplinary research
• Interest in developing new methods for microbial fuel cell technology
• Skills in (bio)informatics would be advantageous
• Working in teams, visiting collaboration partners

The goal of the MAPEX is the system-oriented research and development of materials and processes for sustainable transport and energy applications. The centre merges the know-how of more than 1000 scientific and technical staff, 480 of which are doctoral candidates, active in the fields of natural and engineering sciences as well as mathematics and aiming at a thorough understanding of the process-properties-performance relationships in materials.
MarMic is the International Max-Planck-Research School (IMPRS) with a focus on marine microbiology at the Max Planck Institute for Marine Microbiology. Since its foundation in 2005 the Biomimetics-Innovation-Centre at the Hochschule Bremen has been coordinating research activities in the fields of fundamental interdisciplinary research and development.

The University of Bremen follows a diversity strategy. It strives to increase the number of women in the academy and strongly encourages applications from suitably qualified female candidates. International applications and applications of academics with a migration background are explicitly welcome. Disabled persons with the same professional and personal qualifications will be given preference. The employment is fixed-term and governed by the Act of Academic Fixed-Term Contract, §2 I (Wissenschaftszeitvertragsgesetz – WissZeitVG). Therefore, candidates may only be considered for appointment if they still have the respective qualification periods available in accordance with § 2 (1) WissZeitVG.

We look forward to receiving your e-mail application in English including CV, letter of motivation, and reference contacts!
