Harnessing, and understanding the mechanisms of growth and activity of, biofilms of electroactive bacteria (EAB) on solid electrodes is of increasing interest, for application to microbial fuel and… Expand
The ins and outs of microorganism–electrode electron transfer reactions
Electron transfer between microorganisms and an electrode — even across long distances — enables the former to live by coupling to an electronic circuit. Such a system integrates biological… Expand
Application of Colloidal Gold in Protein Immobilization, Electron Transfer, and Biosensing
Abstract Direct electron transfer between redox proteins and electrodes is of practical and theoretical interest and can be improved by electrode or protein modification. The direct contact of… Expand
Electron transfer mediator systems for bleaching of paper pulp
The participation of biological agents in pulp bleaching systems has received a lot of attention from research teams around the world, driven by the environmental benefits that biobleaching could… Expand
Wiring of pyranose dehydrogenase with osmium polymers of different redox potentials.
In this study, five different flexible osmium based redox polymers were investigated for their ability to efficiently "wire" the oxidoreductase pyranose dehydrogenase (PDH, EC 22.214.171.124) from… Expand
