Clostridium autoethanogenum engineered to produce high yields of acetone and isopropanol from waste CO2 [Registered]

Researchers from the biotech start-up LanzaTech, Northwestern University and the US Department of Energy’s Oak Ridge National Laboratory have engineered a microbe to convert industrial waste gases carbon dioxide and carbon monoxide into acetone and isopropanol (IPA).

Bioengineered bacteria helps produce isopropanol from solar energy [Registered]

They have created a system that uses bacteria (Ralstonia eutropha) to convert solar energy into a liquid fuel. Their work integrates an “artificial leaf,” which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol.
