Project overview

Corynebacterium jeikeium K411 is a lipophilic resident of the human axilla. It is missing a gene coding for a fatty acid synthase and is therefore dependent on exogenous fatty acids. The degradation of lipid compounds in the axilla is mediated by corynebacterial enzymes and contributes to human body odour formation. The project investigates the transcriptional regulation of multiple β-oxidation genes to better understand these degradation processes in the human axilla and their contribution to human body odour.
