About this Research Topic
Fueled by the tremendous progress of molecular biology, bioinformatics, synthetic biology and process intensification, biocatalysis has emerged as a widely used technique in the chemical, biofuel, food and feed, cosmetic and pharmaceutical industries. A large series of successful examples underlines that biocatalysis can improve the sustainability of chemical processes and thus complements other catalytic technologies very successfully. Current processes for the production of chemicals require material-, energy-, time- and space intensive isolation and purification of reaction intermediates, which causes significant waste generation. Hence, cleaner processes must be established by integrating production steps in compliance with sustainability criteria. Nature uses an elegant and efficient strategy to use light – an attractive natural agent – as energy source and to convert it into chemical energy that can later be released to fuel the organisms' activities. Thus, it is not surprising that light has received particular attention for driving or even regulating biocatalytic reactions and thus, manifold concepts for the utilization of light in enzyme-catalyzed reactions have been developed. In recent years, the immense advancement in the field of photobiocatalysis has been fueled by the fast development of enzyme discovery, photocatalysis, chemo/enzyme hybrid catalysts, synthetic biology and electrochemistry. Moreover, various strategies have been developed to efficiently light-regulate enzyme activity using natural photoreceptors or optochemical tools that are promising for the application in biocatalysis.
