The feasibility of recycling CO2 to biofuels in photosynthetic organisms will depend on advances in productivity and product-purification efficiency. Atsumi et al. improve the direct conversion of CO2 by engineering Synechococcus elongatus to produce isobutyraldehyde, which can be easily recovered from the production medium.
