Synthetic Carbon Assimilation Surpasses Nature
For the first time, an international collaboration has demonstrated that synthetic carbon assimilation can operate more efficiently in a living system than its natural counterpart. Researchers in Tobias Erb’s lab at the Max Planck Institute for Terrestrial Microbiology engineered a synthetic metabolic pathway into a bacterium and showed in a direct comparison that it can generate significantly more biomass from the one-carbon compound formic acid and CO₂ than the natural bacterial strain.
