London, Feb 21 (Prensa Latina) Bacteria are known for breaking down lactose to make yogurt and sugar to make beer. Now researchers led by Northwestern University and LanzaTech have harnessed bacteria to break down waste carbon dioxide (CO2) to make valuable industrial chemicals, the British journal Nature Biotechnology revealed Monday. In a new pilot study, the researchers selected, engineered and optimized a bacteria strain and then successfully proved its ability to convert CO2 acetone and isopropanol (IPA).
