  • PRODUCTION OF ISOPRENE UNDER NEUTRAL pH CONDITIONS
    Publication number: 20120045812
    Abstract: Embodiments of the present disclosure relate to a process for producing isoprene from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.

  • INCREASED ISOPRENE PRODUCTION USING THE ARCHAEAL LOWER MEVALONATE PATHWAY
    Publication number: 20100086978
    Abstract: The invention features methods for producing isoprene from cultured cells using a feedback-resistant mevalonate kinase polypeptide, such as an archaeal mevalonate kinase polypeptide. The resulting isoprene compositions may have increased yields and/or purity of isoprene.

  • COMPOSITIONS AND METHODS FOR PRODUCING ISOPRENE FREE OF C5 HYDROCARBONS UNDER DECOUPLING CONDITIONS AND/OR SAFE OPERATING RANGES
    Publication number: 20100048964
    Abstract: The invention features methods for producing isoprene from cultured cells wherein the cells in the stationary phase. The invention also provides compositions that include these cultured cells and/or increased amount of isoprene. The invention also provides for systems that include a non-flammable concentration of isoprene in the gas phase. Additionally, the invention provides isoprene compositions, such as compositions with increased amount of isoprene or increased purity.
