For the first time, gasoline was produced from bacteria. It reveals it a study published in Nature by the group coordinated by the Korean Sang Yup Lee of the Korean Advanced Institute of Science and Technology (Kaist), according to which it is the first step towards sustainable gasoline.

"Growing concerns about the end of fossil fuels and related global environmental problems have focused attention on the need to develop sustainable biofuels from renewable sources." This is how the researchers begin the announcement of their discovery: the development of bacteria of the Escherichia coli strain genetically modified short-chain, therefore suitable for petrol.

In this paper, the Korean researchers describe their detailed strategies for screening enzymes associated with fatty acid production, enzyme and fatty acid engineering to focus carbon flux towards short-chain fatty acid production, and, obviously, the conversion of short-chain fatty acids into gasoline. With this technique you can produce 0,58 grams of gasoline per liter of culture broth.

“It is only the beginning of the works for the production of sustainable gasoline. We are currently working on increasing yield and productivity of bio-gasoline. Nonetheless, we are pleased to report, for the first time, the production of gasoline by the metabolic engineering of E. coli, which we hope will serve as the basis for the metabolic engineering of microorganisms for the production of fuels and chemicals obtained. from renewable resources ", he said researcher.
