Oxidases catalyze the oxidation of molecules directly using dioxygen as the electron acceptor. Gecco biotech has an ever increasing collection of these verstatile enzymes; currently available enzymes are listed below. Our flagship oxidase is 5-Hydroxymethylfurfural oxidase (HMFO).  This enzyme converts HMF into the PEF monomer FDCA and can be used to make bio-based plastic bottles. Oxidases can be used to create many different valuable products, but also the hydrogen peroxide by-product is of interest, for example for electrochemical or colorimetric sensing. The use of ChitO for the detection of cellulase and chitinise degradation products has been extensively describes. The production of hydrogen peroxide can also be exploited for bleaching or anti-microbial purposes.
