The Greenhouse gases, the fuel and our future

Dear readers,

You might be interested to know that US researchers have genetically modified bacteria to eat carbon dioxide and produce isobutyraldehyde - a precursor to several useful chemicals, including isobutanol, which has great potential as a fuel alternative to petrol.

The modified bacteria are highly efficient and powered by sunlight, so a future goal is to set up colonies near to industrial plants. This would allow greenhouse gases to be recycled into useful chemical feedstock - supplying several hydrocarbons that are typically obtained from petroleum.

Cyanobacteria and microalgae that consume CO2 have been identified for a long time, but none produce any liquid molecules that can easily be used as fuel. In the past, attempts have been made to engineer these organisms to produce hydrogen or ethanol, but making the process efficient is still an achievable challenge. There are still much work to be done before the process can be commercialized.
