PhD fellowship in Food Microbiology
Department of Food Science, Section for Food Microbiology, Gut Health and Fermentation invites applicants for a PhD fellowship in vitamin B12 fortification of plant-based foods via fermentation. The project is part of the research project “B12Fundamentals: Solving fundamental challenges for vitamin B12 fortification of plant-based foods”, which is financed by Independent Research Fund Denmark.
Start date is (expected to be) 1 October 2025 or as soon as possible thereafter.
The project
Vitamin B12 (B12) is naturally absent from plants which is a major constraint in the development of nutritious and sustainable plant-based diets. B12 is essential for red blood cell production, and proper nervous system and brain function. With an increasing fraction of especially the younger generation living as vegetarians or with a low intake of animal-derived foods, B12 deficiency is of increasing concern. To address this issue, we will investigate the B12 biosynthetic capabilities of various strains of food-grade bacteria such as Propionibacterium freudenreichii, Priestia megaterium and Acetobacter pasteurianus. To this end, we will employ a combination of genomics, transcriptomics and guided biosynthesis in plant-based matrices to better understand the mechanisms controlling B12 production in candidate bacteria. We will then implement the knowledge in plant-based food prototypes. The project entails two change of environment visits at our collaborators’ labs: Professor Pekka Varmanen’s at the University of Helsinki, Finland and Professor Eddy Smid’s at Wageningen University, the Netherlands.
Who are we looking for?
We are looking for candidates within the field(s) of food microbiology. Applicants can have a background from food science and technology, biology, biotechnology, microbiology, and related fields.
Our group and research- and what do we offer?
Department of Food Science, University of Copenhagen, is recognized for excellence in food research, food science education, and industry collaboration. It covers all disciplines of food science from raw materials to processing and consumption, and is organized in four sections, one of which is the section for “Food Microbiology Gut Health and Fermentation”, where the position is placed. Food fermentations, the use of starter cultures and plant-based foods are strong focus areas. Further information about the Department can be found at https://food.ku.dk/. We are located in Copenhagen.
We offer creative and stimulating working conditions in dynamic and international research environment. Our research facilities include modern laboratories, DNA sequencing facilities and bioinformatics infrastructure.
