Oxygen-embedding enzyme reactions

Enzymes, also known as oxygenases, catalyse under mild conditions the highly specific oxygen-embedding into different basic chemicals as they are interesting for industrial applications. This biocatalytic oxygen-embedding replaces the application of poisonous heavy metal catalysts and complicated multistage-processes of conventional syntheses with high environmental strain.

The main problem of most oxygen-embedding biocatalytic processes, namely the strong product inhibition with its adverse effect on the productivity, was solved in this project for enantionselective styrene-epoxidation. A successful result was the process-integrated, effective and advantageous separation of the product from the production mixture.
Conclusion: Such concepts for integrated oxyfunctionalisation processes as well as the gained productivities are the basis for the development of sustainable and advantageous bioprocesses, that can replace conventional environment-endangering processes of the petrochemistry.
