"W-Biocat - Tungsten Biocatalysis – Heavy Metal Enzymes for
Sustainable Industrial Biocatalysis” (2025-2028)
W-biocat project
W-BioCat is a European Pathfinder research project focused on the development of tungsten containing enzymes for application in a sustainable chemical industry. The project is a collaboration between Delft University of Technology, University of Oxford, Weizmann Institute, University of Florence, Institute of Catalysis and Surface Chemistry PAS, HydRegen, and EvoEnzyme. Our goal is to advance the field of sustainable chemistry and contribute to a cleaner future.

Recombinant W-enzymes
We need to produce W-enzymes using an industrial workhorse micro-organism. Yet, we discovered that W-cofactor biosynthesis is the bottleneck preventing successful production of W-enzymes. We can solve this challenge by using cutting-edge computational enzyme design approaches we recently developed. The W-BioCat strains developed in this project will enable expression of new W-enzymes from genetic databases, and facilitate production of new engineered W-enzymes. The catalytic potential of these new W-enzymes will be established and implemented in new processes.

W-enzymes for industrial use
Europe needs a sustainable chemical industry which will only be realized by new breakthrough technologies. Industrial biotechnology is established in chemical manufacturing, offering more efficient, more specific, safer and less energy demanding production, but is held back by the limited number of enzyme classes in industrial use. The W-biocat project opens up an important new enzyme class of tungsten-containing enzymes (W-enzymes) which catalyse amazing chemical reactions involving challenging low redox potential reduction reactions, but are currently impossible to obtain economically and on scale to match industrial needs.

Development of enzymatic cascades utilizing AOR and H2
W-BioCat will be the breakthrough to make W-enzymes accessible for industry. As a proof of concept, a hydrogen-driven process to convert plant-derived oleic acid to the emollient ester oleyl oleate will be created. Oleyl oleate is used in many cosmetic products used daily by millions of people. This process will be demonstrated in multi-gram yield in scalable, industrially-relevant hydrogenation reactors, together with market research to address a pathway to commercialisation.
