The prospects of synthetic biology for the production of fuel from biomass

When applied to engineering the metabolism of microorganisms, synthetic biology produces a broad spectrum of biomolecules from carbohydrates and, in the near future, from the biomass in general. The markets for biofuels and for chemicals are thus hooked up through a common technological core. Synthetic biology also opens new possibilities for switching from different types of biomass to different products, thus allowing for more flexibility in development strategies and eventually in industrial operations. This opening is welcomed even though the economic and societal environments hardly favors biofuels. A few more years of research and development are needed to bring these new possibilities to industrial maturity. Advanced biofuels will pass the threshold at which they become profitable and will no longer need subsidies. (author)
