Gut Bacteria Make Diesel Fuel
E. coli lives in human intestines, helping us extract vitamin K. Some strains can cause disease. With a little addition of genes from other bacterial species, it can make diesel fuel.
A University of Exeter team has made a strain of E. coli that makes fuel from sugars. It’s no ordinary E. coli: it’s been genetically modified with DNA from no less than four other kinds of bacteria. Each of the other bacterial species exists in nature and does part of the chemical process that takes a relatively simple carbon molecule (sugar) and turns it into the long-chain ones that go into fuel.
