We are seeking a highly motivated PhD candidate to join a cutting-edge research project starting in April 2026 to investigate the anaerobic electroactive physiology, and related ecological interactions, in yeast. This project is part of a Dutch research council (NWO) funded M1 project, and will be conducted at the Laboratory of Microbiology at Wageningen University.
Extracellular electron transfer is a trait well-established in anaerobic metal-reducing bacteria, enabling them to respire anoxically with metals, grow in bio-electrochemical systems, and playing a role in microbial community interactions. Several microbial eukaryotes have shown electroactive traits as well, but their physiological function and underlying mechanisms remain poorly understood. Insight in anaerobic eukaryotic electroactive metabolism can fundamentally transform our understanding of their physiological capabilities, their ecological role, and unveil their potential applications.
Aim and approachThe core aim of this project is to gain mechanistic insight into the electroactive metabolism of the yeast
Saccharomyces cerevisiae under anaerobic conditions
. By combining bio-electrochemical experiments, with omics and genetic engineering approaches, you will unravel the mechanisms that underly extracellular electron transfer in yeast, and assess its physiological impact. Subsequently, you will establish yeast in synthetic co-cultures with anaerobic bacteria, assessing the role of electroactive metabolism in cross feeding, and gaining insight in currently poorly explored anaerobic eukaryote-prokaryote interactions. You will work at the exciting interface of Microbial Physiology, Systems Biology, and Biotechnology, pushing the boundaries of our understanding of how fundamental biological processes shape natural ecosystems, and enable novel biotechnological applications.
Key responsibilities: - Perform bio-electrochemical cultivations with yeast (S. cerevisiae) to study its electroactive physiology in various conditions.
- Design and conduct syntheticco-culture experiments with yeast and anaerobic prokaryotes, and study their (cross feeding) interactions.
- Apply omics-based and genetic engineering approaches to investigate mechanisms underlying bio electrochemical growth, and explore interactions in the established co-cultures.
-
Disseminate research findings through publications, conference presentations, and research meetings.
- Contribute to teaching and supervision of students.
