E. coli taught to produce biofuels


Scientists from the University of Exeter with the Shell oil company found a way to make a normal bacterium E. coli (or enterohemorrhagic bacteria, or simply E. coli) to produce biofuels, which can be refilled with cars, trucks cars and even airplanes.

Up until now, biofuels produced from the chain hydrocarbon compounds of irregular shape and size. This allowed the most modern internal combustion engines it to “digest”. This fuel does work, but the engines are based on it are usually obtained ineffective and wear out very quickly.

For the use of biofuels as the main alternative to fossil fuel engines need to specifically upgrade, or the fuel itself must undergo further complicated stages of processing, so that it eventually turned more suitable for these purposes.


John Love, a leading specialist research

To circumvent this requirement, scientists from the University of Exeter, led by John Lava took genes camphor tree, blue-green algae and put them together with a chain of DNA of Escherichia coli. When the resulting “modified” the bacterium E. coli were fed glucose, enzymes produced by it processed sugars into fatty acids and then to hydrocarbons, which, by their structural and chemical composition have turned out the same as that found in traditional commercial fuel.

“We are biologically able to reproduce the fuel, which produce and sell energy companies” – says Love.

Currently, a team of scientists thinks about how to increase the scale required for mass production of hydrocarbon.

Scientists fed E. coli glucose vegetable production, but Love believes that, due to the subsequent experiments on an industrial scale bacterium can be processed to make fuel and hay and manure. This means that for the production of biofuels will not need to use additional territory to seed feedstock, which would otherwise be used for food crops sowing.

Professor Paul Freemont, of Imperial College London loved this discovery. The scientist spoke in support of the fact that this approach will allow in the future to produce not only biofuels but also be able to open the doors to its basis it was possible to create materials such as plastics, solvents and detergents, which are usually made from recycled oil.

The research work is partially funded by the University of Exeter scientific division of energy company Shell.
