Harrison Dillon and Jonathan Wolfson, founders of biotechnology firm Solazyme Inc., USA. Wolfson (right) is holding a vessel containing algae biodiesel. Algae are high-yielding photosynthetic micro-organisms. They can be cultivated to produce edible oils, and biodiesel. Unlike fossil fuels, biodiesel is non-toxic and biodegradeable. Algaecan also be dried and used as a fertiliser, animal feed or burned as biomass. Solazyme is using synthetic biology and genetic engineering to produce novel strains of algae. Photographed in 2008.
