Electricity from methane by Methylococcus capsulatus (Bath) and Methylosinus trichosporium OB3b.

Given the difficulties valorizing methane (CH) via catalytic routes, this study explores use of CH-oxidizing bacteria ("methanotrophs") for generating electricity directly from CH. A preconditioned methanotrophic biofilm on 3D nickel foam with reduced graphene oxide (rGO/Ni) was used as the anode in two-compartment microbial fuel cells (MFCs). This study demonstrates a proof of concept for turning CH into electricity by two model methanotrophs including Methylosinus trichosposium OB3b and Methylococcus capsulatus (Bath).
