Researchers in the United Kingdom have figured out how to produce biodiesel from E. coli bacteria. This news release from the University of Exeter says the work with Shell Oil makes a product almost exactly the same as petroleum diesel, removing any blend limits other biodiesel forms might require:

Professor John Love from Biosciences at the University of Exeter said: “Producing a commercial biofuel that can be used without needing to modify vehicles has been the goal of this project from the outset. Replacing conventional diesel with a carbon neutral biofuel in commercial volumes would be a tremendous step towards meeting our target of an 80% reduction in greenhouse gas emissions by 2050. Global demand for energy is rising and a fuel that is independent of both global oil price fluctuations and political instability is an increasingly attractive prospect.”

The release goes on to talk about how E. coli bacteria turn sugars into fat, and thus, the oils to serve as a feedstock for the biodiesel.
