Researchers from the University of California in Los Angeles found a way to create genetically modified bacteria called cyanobacterium, which consume carbon dioxide and produce the liquid fuel isobutanol, reported Science Daily.

The research originally published on Wednesday in the journal Nature of Biotechnology states that consumption of carbon dioxide is directly powered by the sun, a process similar to photosynthesis.

The new method has two major advantages: it recycles carbon dioxide which reduces greenhouse gas emissions and it uses solar energy to convert carbon dioxide to liquid fuel which can be used in automobiles.

James C. Liao, team leader of the researchers, said the new process will avoid biomass deconstruction which is a major economic barrier for biofuel production. The newly discovered process can lessen expenses and speed up the creation of an alternative fuel.

Biofuels are derived from plants or algae, and the process involves several phases before fuel is produced.

Mr. Liao and his group discovered the process by genetically increasing the quantity of the carbon dioxide-fixing enzyme RuBisCO in cyanobacterium Synechoccus elongates. They merged the genes from other microorganisms and created a strain that processes carbon dioxide and sunlight to produce isobutyraldehyde gas.

The bacteria can instantly produce isobutanol. However, Mr. Liao admitted that currently, it is easier to use the existing method of isobutanol conversion since the new method needs further testing.

The perfect use for this system is in a power plant that emits carbon dioxide as it will allow greenhouse gases to be confined and reprocessed into liquid fuel.
