Phototriggering lignin peroxidase with nanocatalysts to convert veratryl alcohol to high-value chemical veratryl aldehyde

• 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 O-2 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. (C) 2018 Elsevier Ltd. All rights reserved.
