MULTIELECTRON TRANSFER ENZYMIC REACTIONAL SYSTEM FOR PHOTOBIOREACTOR

摘要

PROBLEM TO BE SOLVED: To provide both a multielectron transfer enzymic reactional system for a photobioreactor in order to improve the electron transfer efficiency and enzymic reactional efficiency so as to solve disadvantages in that the electron transfer efficiency and enzymic reactional efficiency are low when a one-electron transfer type electron mediator is used without taking a desired number of electrons in the electron transfer enzymic reaction using the electron mediator and the photobioreactor based on the system. SOLUTION: This multielectron transfer enzymic reactional system is characterized by bringing an aqueous medium containing a raw material substrate and the multielectron mediator into contact with a photoexcited type electron supplying source irradiated with light, accepting electrons from the electron supplying source by the multielectron mediator, supplying the electrons to an enzyme, thereby chemically converting the raw material substrate by the enzyme utilizing the electrons and providing a produced substance. The photobioreactor is based on the multielectron transfer enzymic reactional system.
