LanzaTech, renowned for converting industrial waste gases into ethanol, is venturing into microbe-based food production to address global protein demands and reduce climate impact. By cultivating Cupriavidus necator, a bacterium capable of producing a powder that is over 85% protein, LanzaTech aims to create sustainable food alternatives for humans and animals. This innovation aligns with the push to cut greenhouse gas emissions from the global food system, which accounts for 25–35% of human-caused emissions, particularly from animal agriculture. Unlike traditional protein sources, bacteria-based food requires less land and water while emitting fewer greenhouse gases. LanzaTech’s approach capitalises on its expertise in microbial fermentation, positioning it as a promising player in the alternative protein market, alongside companies like Air Protein and Solar Foods. While still in early development, with a pilot facility in Illinois producing one kilogram of protein daily, LanzaTech plans to scale up operations, aiming for a commercial plant by 2026. CEO Jennifer Holmgren emphasises the potential of microbial protein to feed the world sustainably, though challenges like taste, texture, and regulatory approvals remain to be addressed.
