Patent number: 9296850Abstract: It has been found that certain cells in culture can convert more than about 0.002 percent of the carbon available in the cell culture medium into isoprene. These cells have a heterologous nucleic acid that (i) encodes an isoprene synthase polypeptide and (ii) is operably linked to a promoter. The isoprene produced in such a cultured medium can then be recovered and polymerized into synthetic rubbers and other useful polymeric materials. The synthetic isoprene containing polymers of this invention offer the benefit of being verifiable as to being derived from non-petrochemical based resources. They can also be analytically distinguished from rubbers that come from natural sources. 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 ?13C value of greater than ?22%.Type: GrantFiled: January 26, 2015Date of Patent: March 29, 2016Assignees: The Goodyear Tire & Rubber Company, Danisco US, Inc.Inventors: Frank J. Feher, Gregory M. Whited, Gopal K. Chotani, Fernando Valle, Carol Fioresi, Karl J. Sanford, Joseph McAuliffe, Marguerite Cervin, Aaron S. Puhala, Andrei Miasnikov, Ilana S. Aldor

Publication number: 20130122562Abstract: This invention relates to a recombinant microorganism capable of producing isoprene and isoprene production with the use of such recombinant microorganism with good efficiency. In this invention, the acetoacetyl-CoA synthase gene encoding an enzyme capable of synthesizing acetoacetyl-CoA from malonyl-CoA and acetyl-CoA and one or more genes involved in isoprene biosynthesis that enables synthesis of isoprene from acetoacetyl-CoA are introduced into a host microorganism.Type: ApplicationFiled: August 3, 2012Publication date: May 16, 2013Applicant: Danisco US Inc.Inventors: Ilana S. Aldor, Zachary Q. Beck, Michael C. Miller, Caroline M. Peres

Publication number: 20110237769Abstract: It has been found that certain cells in culture can convert more than about 0.002 percent of the carbon available in the cell culture medium into isoprene. These cells have a heterologous nucleic acid that (i) encodes an isoprene synthase polypeptide and (ii) is operably linked to a promoter. In some cases, these cells are cultured in a culture medium that includes a carbon source, such as, but not limited to, a carbohydrate, glycerol, glycerine, dihydroxyacetone, one-carbon source, oil, animal fat, animal oil, fatty acid, lipid, phospholipid, glycerolipid, monoglyceride, diglyceride, triglyceride, renewable carbon source, polypeptide (e.g., a microbial or plant protein or peptide), yeast extract, component from a yeast extract, or any combination of two or more of the foregoing. The isoprene produced in such a cultured medium can then be recovered and polymerized into synthetic rubbers and other useful polymeric materials.Type: ApplicationFiled: June 30, 2009Publication date: September 29, 2011Applicant: The Goodyear Tire & Rubber CompanyInventors: Frank J.
