Production of fine chemicals from biomass, in particular lignin fraction, is paramount to the development of a sustainable bioeconomy. Herein, a photosystem capable of generating H₂O₂ in situ from the photoreduction of O₂ is presented, which is subsequently used to activate lignin peroxidase enzyme. The active enzyme selectively converts veratryl alcohol into veratryl aldehyde, a high-value flavoring and fragrance compound. This unique reaction scheme increased significantly the process greenness and safety credentials.
