Publication number: 20110201093Abstract: The present invention is directed to the enhanced production of ethanol from fermentation using an ethanol producing microorganism. In particular, the present invention provides a process for the enhanced growth and metabolism of an ethanol producing microorganism (e.g., yeast), for the purpose of increasing or enhancing ethanol production, both in terms of total ethanol produced and in terms of the time required for ethanol producing microorganisms to convert carbohydrates and/or sugars to end products (i.e., ethanol). In accordance with this invention bicarbonate ions are used to enhance ethanol fermentation and/or reduce the time required for ethanol producing microorganisms to convert carbohydrates and/or sugars to end products, i.e., ethanol. The present invention can also be used for enhancing fermentation end products in, for example, the fuel ethanol, industrial, cheese, brewing, and wine making industries.Type: ApplicationFiled: April 28, 2011Publication date: August 18, 2011Applicant: CHURCH & DWIGHT CO., INC.Inventors: Melvin H.

Publication number: 20110150850Abstract: The invention is in the field of use of engineered microbes for the delivery and administration of therapeutic peptides or proteins to humans or animals suffering from a disease, or the use of engineered microbes for the delivery of antigens such as for vaccination purposes. More in particular, the invention relates to a recombinant microbe that has reduced capacity of colonizing the mucosa in comparison to its wild type ancestor, in particular when residing in the alimentary tract as part of a treatment or vaccination of a human or animal. In particular, the recombinant microbe contains an inactive thymidylate synthase gene that causes the reduced capability for the microbe to colonize in the alimentary tract. The invention also covers the use of said recombinant microbes comprising nucleic acids or vectors for expressing heterologous or homologous proteins; and also for delivery, especially therapeutic delivery, of the said proteins to animals or humans.Type: ApplicationFiled: September 29, 2009Publication date: June 23, 2011Inventor: Lothar Steidler
