PhD Position on Polymer Biodegradation and Extracellular Enzymes in Aquatic Environments

Are you passionate about conducting fundamental research that creates an impact on
sustainability? The Centre for Microbiology and Environmental Systems Science at the University of Vienna is offering a PhD position to explore the role of extracellular enzymes in the biodegradation of water-soluble polymers in aquatic environments.

The project

Water-soluble polymers (WSPs) are essential for numerous applications, and, after use, they enter wastewater and freshwater systems. To enable sustainable end-of-life solutions for WSPs, a fundamental understanding of the extracellular enzymes in these systems is needed.
This project aims to link WSP biodegradation with the activity and identity of extracellular enzymes. Specifically, you will employ a multi-faceted approach based on enzyme inhibition, activity assays based on substrates relevant to WSPs, and enzyme isolation and identification to reveal key enzymes and provide a molecular-level understanding of WSP biodegradation in wastewater and freshwater systems.

We Are

The research group is part of the Centre for Microbiology and Environmental Systems Science at the University of Vienna (Austria). They are dedicated to conducting cutting-edge research at the intersection of chemistry, microbiology, and environmental science and informing solutions to current environmental challenges.

We Offer
