The invention features methods producing isoprene and a co-product, such as ethanol, 1,3- propanediol, or hydrogen from cultured cells. The invention also provides compositions that include these cultured cells. The invention provides compositions comprising isoprene and ethanol, isoprene and 1,3-propanediol, and isoprene and hydrogen. Additionally, the invention provides methods of co-producing isoprene and ethanol, isoprene and 1,3-propanediol, and isoprene and hydrogen by culturing cells under conditions suitable for co-production of isoprene and ethanol, isoprene and 1,3-propanediol, and isoprene and hydrogen. L'invention porte sur des procédés de production d'isoprène et d'un co-produit, tel que l'éthanol, le 1,3-propanediol ou l'hydrogène à partir de cellules cultivées. L'invention porte également sur des compositions qui contiennent ces cellules cultivées. L'invention porte sur des compositions comprenant de l'isoprène et de l'éthanol, de l'isoprène et du 1,3-propanediol, et de l'isoprène et de l'hydrogène. De plus, l'invention porte sur des procédés de co-production d'isoprène et d'éthanol, d'isoprène et de 1,3-propanediol et d'isoprène et d'hydrogène par la culture de cellules dans des conditions appropriées pour la co-production d'isoprène et d'éthanol, d'isoprène et de 1,3-propanediol, et d'isoprène et d'hydrogène.
