Eco Tech: Sun-powered bacteria convert greenhouse gases into fuel

CO2-eating bacteria produce fuel.

With fossil fuels depleting at a rate much more than predicted, researchers in different parts of the globe are working on means to generate alternative fuel from sources as small as bacteria. A team from researchers from US has genetically modified bacteria to eat carbon dioxide and produce isobutyraldehyde, which can further be used to produce isobutanol.

The modified bacteria are highly efficient in the conversion process and are powered by sunlight. Cyanobacteria and microalgae have been identified to consume CO2 for a long time. However previous researches on using them to produce fuel as an output haven’t been fruitful.

The US research team was successful in genetically modifying bacteria to produce fuel using a process that is around 10 times faster than hydrogen production and about 100 times faster than genetically engineered ethanol production.
