“Diesel could put Clostridium back in business"

A paper by Dean Toste, Harvey Blanch and Douglas Clark in the 8 Nov 2012 issue of Nature describes work in which Blanch and Clark developed a way of extracting the acetone and butanol from a fermentation mixture produced by Clostridium acetobutylicum while leaving most of the ethanol behind, while Toste developed a catalyst that converted this ideally proportioned brew into a mix of long-chain hydrocarbons that resembles the combination of hydrocarbons in diesel fuel.
