Genetically Modified Organisms (GMOs) are living organisms whose genome has been artificially modified by man (through biotechnology), for example to improve resistance to plagues in the case of crops.
GMOs also include organisms developed for the processing of biofuels, a very promising area of research and development. Hopefully, things like drought, disease tolerance, and adaptation to new ecosystems, rather than pesticide resistance, will become a focus of GMO crop development in the future.

- Scientists find bugs that eat waste and excrete petrol, 14 June 2008 in The Times Online. The Silicon Valley company LS9 is using genetically modified microorganisms to produce 'renewable petroleum'. However, the technology is still not ready for commercialization.

- World Rainforest Movement calls for ban on genetic engineering of trees in Open letter to all members of the Convention on Biological Diversity (CBD) Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) (February 2008), including genetic modification to make certain trees more suited to the production of cellulosic ethanol. The statement read in part:
- "research is being carried out to develop eucalyptus trees with a higher cellulose content for the production of cellulose for paper and for the production of ethanol. This would mean reducing the amount of lignin, the component that provides trees with structural strength, thus making them more susceptible to suffering -- as well as causing -- serious damage during wind storms."[1]
- Efficient Biofuel Made From Genetically Modified E. Coli Bacteria, 7 January 2008 from ScienceDaily, reported that scientists at the California university UCLA "have developed a new method for producing next-generation biofuels by genetically modifying Escherichia coli bacteria to be an efficient biofuel synthesizer." The bacteria can create branched-chain alcohols, such as isobutanol, which could be more useful as liquid fuels than ethanol.
