Toronto # Methanivore: a comprehensive solution to landfill gas emissions through bacterial metabolic engineering # Landfill gasses (LFG) account for 23% of Canada’s methane emissions, a potent greenhouse gas contributing to global warming. Current methods–methane combustion–release excess carbon dioxide and are ecologically harmful. Our solution involves optimizing a genetically-engineered Escherichia coli strain (T-B18) which metabolizes methanol via the ribulose monophosphate pathway (RuMP). We also demonstrated a process concept where methane is separated from LFG using cellulose acetate membranes then converted into methanol by a catalytic reactor, enabling bacterial consumption. ...
