We determined that graphene oxide reduction by Shewanella oneidensis MR-1 requires the Mtr respiratory pathway by analyzing a range of mutants lacking these proteins. Electron shuttling compounds increased the graphene oxide reduction rate 3- to 5-fold. These results may help facilitate the use of bacteria for large-scale graphene production.
