Not all bacteria are harmful. In fact, some provide beneficial effects to the host organism and these are called probiotic bacteria. During her studies, Katrine has identified novel probiotic strains that increase lifespan and protect the small worm C. elegans against methicillin-resistant Staphylococcus aureus (MRSA) infection. To gain a deeper understanding of the underlying molecular mechanisms involved, she looked at changes in the levels of small molecules (metabolites) in C. elegans upon consumption of probiotics. The analysis has identified a number of metabolites and pinpointed mechanisms that might be causally involved in the beneficial longevity response and the protective effect against MRSA. These discoveries will contribute to the understanding of probiotic mechanisms of action, which is important for developing future alternatives to traditional antibiotics.

The PhD degree was completed at the Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.
