Our research is centered around the comprehensive study of Extracellular Polymeric Substances (EPS). Through a combination of highly precise methods, we aim to thoroughly characterize both well-established and newly discovered EPS variants with the potential for diverse and sustainable applications across various industries.

A key aspect of our work involves the development of a versatile multi-EPS toolbox, enabling us to create mixtures precisely tailored to meet the specific demands of each application. By leveraging this toolbox, we can ensure that the EPS utilized in various industrial processes are optimized for their intended purposes.

To align with industrial standards, we improve the fermentation process and downstream processing of the respective EPS. These improvements guarantee greater scalability, efficiency, and consistency, making the EPS production more viable and economically feasible for large-scale applications.
