Enzyme Ecology
Our research is focused on the enzymes that catalyse degradation of plant cell walls in nature as well as in industrial biorefineries.
The aim is to both understand the molecular mechanisms and the systems in which the enzymes work. Our laboratories are equipped with specialised instruments that allow for study the role of oxygen in the degradation processes.
Special attention is given to enzymes called lytic polysaccharide monooxygenases (LPMOs). These enzyme are mononuclear copper enzymes that use oxygen-species for catalysis.
LPMOs are likely to have several functions in biology and are important for saprotrophic fungal lifestyle. Importantly, they initiate degradation of cellulose by cleaving glycosidic bonds at places that are not accessible cellulose hydrolases.

Master projects
Every year we develop a list of project ideas. You can use the Thesis Idea Catalogue to get inspiration for you own project, or formulate your own project. You are always welcome to come by our offices to discuss your ideas.
Bachelor projects
We are always looking for students who want to try out production, purification, and characterization of enzymes. These projects offer a great opportunity to develop a range of laboratory skills, providing tangible results, such as colonies on a plate, bands on a PAGE-gel, and color formation from enzymatic assays.
In the Enzyme Ecology group, our research focuses on enzymes that are working on natural polymers, and each project will work towards an experiment that test such an activity on a heterogeneous (dirty) sample. Join us to gain valuable hands-on experience and contribute to meaningful research.
Examples of enzymes:
- LPMOs that oxidize and degrade insoluble fibers (key enzymes in recycling of biomass in nature and in industrial setting)
- Glucose oxidases, unexpectedly found in anaerobic environments
- Glycan hydrolases that degrade glycan matrix in biofilms
- Carbonic anhydrases, which can capture CO₂ and convert it to bicarbonate
