Biodiesel producing bacteria
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the prospects for a new store of energy - biodiesel as produced by genetically modified bacteria. In terms of the Atlas of Technological Megatrends it shows how information processing can create organisms to produce matter (biodiesel) to serve as energy store.
The previous Newsbrief, Vol. 5, No. 1, dealt with the production of hydrogen through bacterial action. The continuing interest in renewable energy systems is now focusing attention on biodiesel.
Biodiesel can be produced in different ways. These include:
  • Chemically - mixing vegetable oil and alcohol
  • Biologically - using algae
  • Microbiologically - using bacteria
In 2008 and 2010, researchers announced that they had succeeded in genetically engineering E. coli, to digest simple sugars from plant waste and turn them into biofuel. This is claimed to be the first one-step conversion of a renewable non-food plant to fuel. The altered E. coli can receive various inputs, including partially processed material like glucose and ethanol, and produce fatty acid methyl esters, or biodiesel. (Johnston, Casey "Engineering E. coli to produce biodiesel", Nature, 2010. DOI: 10.1038/nature08721)
From the point of view of fuel production this process is at a very early stage of development. In terms of NASA's nine technology readiness levels, it lies at about TRL 3. As E.coli is a very well studied bacteria, technology explorers could expect further refinement. The fact that it can be readily engineered indicates possibly enhanced competition with traditional biodiesel manufacturing technology. However, a possible negative image associated with E. coli may hinder unqualified acceptance.
