20100113846CONVERSION OF PRENYL DERIVATIVES TO ISOPRENE - The present invention provides methods for producing derivatives from cultured cells. In addition, the present invention provides methods for conversion of prenyl deerivatives, obtained from biological or petrochemical sources, to isoprene by employing chemical or biological catalysts. The present invention also provides compositions that include the cultured cells or isoprene or prenyl derivatives produced there from.05-06-2010
20100167370REDUCTION OF CARBON DIOXIDE EMISSION DURING ISOPRENE PRODUCTION BY FERMENTATION - The present invention provides methods for increasing the amount of isoprene produced by cultured cells with only a minimal increase in carbon dioxide emitted, thereby resulting in process having a greater yield of isoprene relative to carbon dioxide. In addition, the present invention provides compositions that include the cultured cells or isoprene produced there from.07-01-2010
20100196977METHODS OF PRODUCING ISOPRENE AND A CO-PRODUCT - 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.08-05-2010
20110040058POLYMERIZATION OF ISOPRENE FROM RENEWABLE RESOURCES - The invention features compositions and methods for producing polymers of isoprene derived from renewable resources such as isoprene produced from cultured cells that use renewable carbon sources. A starting isoprene composition, such as a bioisoprene composition, is distinguished from petroleum based isoprene by the purity profile (such as lower levels of certain C5 hydrocarbons other than isoprene, presence of certain compounds associated with the biological process for production) and the relative content of the carbon isotopes. Polymers obtained by polymerization of such starting isoprene composition according to this invention, such as a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene, are distinguishable from isoprene containing polymers from petrochemical resources. The present invention more specifically discloses a polyisoprene polymer which is comprised of repeat units that are derived from isoprene monomer, wherein the polyisoprene polymer has δ02-17-2011
20110046422FUEL COMPOSITIONS COMPRISING ISOPRENE DERIVATIVES - The invention provides for methods, compositions and systems using bioisoprene derived from renewable carbon for production of a variety of hydrocarbon fuels and fuel additives.02-24-2011
20110195472MEMBRANE BIOREACTOR FOR INCREASED PRODUCTION OF ISOPRENE GAS - The invention provides improved methods for the production of isoprene from biological materials.08-11-2011
