Exciting Enzymes: Current State and Future Perspective of Photobiocatalysis

The recent increase of interest in photocatalysis spread to biocatalysis and triggered a rush for the development of light-dependent enzyme-mediated or enzyme-coupled processes. After several years of intense research on photobiocatalysis, it is time to evaluate the state of the field in a structured manner. In this Perspective, we suggest to...

Study on green extraction of limonene from orange peel and cascade catalysis to produce carvol and carvone in deep eutectic solvents

Carvol and carvone are oxidation products from the natural product limonene. They are important raw materials for the flavours and fragrances industry and also act as pharmaceutical active ingredients. Orange waste peels possibly represent an attractive source for limonene, but studies on valorizing orange peel wastes are rare. In this study,...

Photoenzymatic Production of Next Generation Biofuels from Natural Triglycerides Combining a Hydrolase and a Photodecarboxylase

A photobiocatalytic cascade transforming natural triglycerides into alkanes/alkenes is proposed. Starting from natural triglycerides, free fatty acids have been obtained using lipases. The free fatty acids were then, in a photoenzymatic step, decarboxylated into the C1-shortened alkanes using a recently described photodecarboxylase from...

Cascading g-C₃N₄ and Peroxygenases for Selective Oxyfunctionalization Reactions

Peroxygenases are very interesting catalysts for specific oxyfunctionalization chemistry. Instead of relying on complicated electron transport chains, they rely on simple hydrogen peroxide as the stoichiometric oxidant. Their poor robustness against H₂O₂ can be addressed via in situ generation of H₂O<sub>2<...

Peroxygenase-Catalysed Epoxidation of Styrene Derivatives in Neat Reaction Media

Biocatalytic oxyfunctionalisation reactions are traditionally conducted in aqueous media limiting their production yield. Here we report the application of a peroxygenase in neat reaction conditions reaching product concentrations of up to 360 mM.
