My research is focused on the field of heterogeneous biocatalysis. The use of different enzyme immobilization and co-immobilization strategies, the development and modification of supports and the characterization of biocatalysts were the main points to highlight out of it. Since December 2021, I been working at the Chair of Chemistry of Biogenic Resources (TUMCS) leading a project for the co-immobilization of enzymes involved in synthetic cascades reactions developed at the chair. The preparation of optimal co-immobilized cascades will allow to use, recover and reuse the biocatalysts and benefit from all the advantages of immobilization and co-immobilization. This will reduce the cost of processes and improve reaction yields, providing a promising green alternative to the traditional chemical industry.
