Give me that CO2 - I'm hungry
Researchers hope to tap synthetic life-forms to convert atmospheric carbon dioxide, or CO2, into food, fuel and organic chemicals that humans can use. But many previous attempts, like a 2016 effort to synthesize sugar from CO2 in bacteria, have seen limited success.
In a study published Wednesday in Cell, researchers from the Weizmann Institute of Science in Israel report that they have created a strain of E. coli that eats CO2 for energy, rather than organic compounds like sugars and fats.
And while the study comes with a major caveat — the process currently produces more CO2 than it consumes — the research team hopes their work can provide a foundation for carbon-neutral energy sources in the future.
