Development of heterogenous cascade for photobiocatalytic oxyfunctionalizations

PhD defence, Friday 24 March 2023. Piera De Santis

Piera De Santis

During her PhD studies, Piera De Santis investigated enzyme immobilization and the in situ production of hydrogen peroxide to overcome the hurdles that still hinder unspecific peroxygenase (UPOs) practical application at the industrial level. Simultaneously, during her secondment at the University of Graz, her research studies focused on optimizing the modular photo-electron shuttling (MPS) system developed to regenerate nicotinamide cofactors.

The results obtained from both studies will improve the process stability and cost-effectivity of biocatalytic oxyfunctionalization, enhancing their application at the industrial scale and a further step into the revolutionary green chemistry approach.

The PhD degree was completed as part of a double degree (cotutelle) cooperation between Biological and Chemical Engineering, Faculty of Technical Sciences, Aarhus University and University of Graz, Austria.

This summary was prepared by the PhD student.
