Cyanobacteria are an attractive candidate for renewable production of microbe-derived chemicals, thanks to their plantlike power that converts sunlight and carbon dioxide to energy. But scaling up production is difficult, partially because of sunlight limitations in large industrial facilities. Shota Atsumi at the University of California, Davis, is seeking to bypass that problem by engineering the cyanobacteria species Synechococcus elongatus to metabolize a second carbon source, glycerol: a cheap and . . .
