Patent number: 9593320Abstract: The present invention provides methods and compositions for the production of mature proteases in bacterial host cells. The compositions include modified polynucleotides that encode modified proteases, which have at least one mutation in the pro region; the modified serine proteases encoded by the modified polynucleotides; expression cassettes, DNA constructs, and vectors comprising the modified polynucleotides that encode the modified proteases; and the bacterial host cells transformed with the vectors of the invention. The methods include methods for enhancing the production of mature proteases in bacterial host cells e.g. Bacillus sp. host cells. The produced proteases find use in the industrial production of enzymes, suitable for use in various industries, including but not limited to the cleaning, animal feed and textile processing industry.Type: GrantFiled: July 31, 2015Date of Patent: March 14, 2017Assignee: DANISCO US INC.Inventors: Eugenio Ferrari, Carol Fioresi, Anita van Kimmenade

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.
