Design of a Highly Efficient O2 Cathode Based on Bilirubin Oxidase from Magnaporthe oryzae



original image

Fungi for the better: The so far highest known current density (1.37 mA cm−2) for the enzymatic O2 reduction under physiological conditions is reported. This is achieved by the design of a new redox polymer with an increased catalytic site density and by using a new bilirubin oxidase (BOD) from Magnaporthe oryzae.
