COVER Brown seaweed (Macrocystis pyrifera), commonly known as giant kelp, off the coast of Chiloe Island, Chile (image width ~1 meter). Traditionally, seaweed has been ignored as a source of renewable fuel and chemical compounds for bioconversion, because its primary sugar component is not easily fermented. Wargacki et al. engineered a microbe to extract sugars from brown seaweed and convert them into low-carbon, renewable fuels and chemicals. See page 308. Photo: Julián Fernández
