2 PhD positions in the field of C1-carbon metabolism of anaerobic micro-organisms: Netherlands

We are looking for two enthusiastic PhD candidates with strong interest in microbiology, specifically on the application of omics approaches (genomics, transcriptomics, proteomics) to study the microbial physiology of anaerobes. The candidates should have a good background in microbiology, strong motivation, good communication skills and ability for teamwork and cooperation.

Project 1 – Methanol metabolism of sulfate-reducing bacteria

Methanol is an excellent substrate for microbial growth in many different environments. Anaerobic methanol degradation is well studied in methanogens and acetogens. However, methanol is not a known common substrate for sulfate-reducing bacteria. Only a few sulfate reducers are described to be able to utilize methanol, which include some Gram-negative (Desulfovibrio) and Gram-positive (Desulfotomaculum) bacteria. Recently, we performed a proteomics study, which revealed that Desulfotomaculum kuznetsovii possesses two methanol-degrading pathways: involving a methyltransferase system and a methanol dehydrogenase. We aim to further describe these pathways and to study the methanol metabolism of other methanol-utilizing sulfate-reducing bacteria, including the isolation of novel anaerobes from different environments (including extreme environments). This research is also of practical importance as sulfate-reducing bacteria can be exploited in sulfur biotechnology to remove sulfur and metals from waste streams.
This project is part of the Gravitation Research Program SIAM – Soehngen Institute of Anaerobic Microbiology (anaerobic-microbiology.eu/scientists/). The PhD project will be developed at the Laboratory of Microbiology at Wageningen University & Research (WUR).

Project 2 – Novel biocatalysts for syngas conversion

The diversity of anaerobic carboxydotrophic microorganisms (i.e. microorganisms that can use CO as carbon and energy source) is largely underestimated, and a small number species are known to utilise CO. Many of these species are susceptible to high concentrations of CO and/or show low conversion rates, which become limiting factors for the development of biotechnological processes. In addition to this, the spectrum of products that can be naturally produced from CO by pure cultures of available microorganism is rather narrow. In this project we want to characterize the metagenome of environments in which CO is potentially present (e.g. volcanos, thermal vents) and to target the isolation of novel microorganisms able to use this compound. Thermophilic microorganisms have higher substrate conversion rates than mesophiles, and will be given preference in this project.
This project is part of the Perspectief Program MicroSynC – Novel Approaches for Microbial Syngas Conversion to Chemical Building Blocks. The PhD project will be developed at the Laboratory of Microbiology at Wageningen University & Research (WUR).
