Capturing carbon with enzymes

A promising technique by CO2 Solution

The research company CO2 Solution of Quebec City, Canada, has developed a new way to capture carbon dioxide from smokestacks. It has genetically engineered E. coli bacteria to produce an enzyme that converts carbon dioxide into bicarbonate, a raw material that can be sequestered underground or used to produce substances such as baking soda, chalk, or limestone. The main advantage of a bioreactor containing this enzyme, compared to other systems, is that it does not require separation of the carbon dioxide. It can be used for any gaseous effluent containing carbon dioxide.
