University of Edinburgh Researchers Develop Microbial Method for Sustainable Hydrogenation Using Waste Bread
Researchers at the University of Edinburgh have created a microbial hydrogenation process using waste bread, leveraging Escherichia coli bacteria to generate hydrogen gas. This method replaces traditional fossil fuel-derived hydrogen, typically produced under high temperature and pressure, reducing energy use and carbon emissions.
The process uses anaerobic fermentation in a single vessel, achieving hydrogenation at ambient conditions. It incorporates discarded bread, transforming food waste into a valuable resource and potentially realizing carbon-negative outcomes.
The technology has applications in food, pharmaceuticals, and specialty chemicals. Supported by UKRI and ERC funding, the team plans to expand substrate options and optimize microbial strains, promoting decentralized manufacturing.
