  • Publication number: 20090170174
    Abstract: 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.

  • Patent number: 7022513
    Abstract: The present invention makes available a rapid, reproducible, robust assay system for screening and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular protein, e.g., a receptor or ion channel. The subject assay enables rapid screening of large numbers of compounds to identify those which act as an agonist or antagonist to the bioactivity of the cellular protein. In particular, the assay of the invention makes use of a cell that harbors a protein that is responsive to a cellular signal transduction pathway. The protein is operatively linked to a polypeptide which causes a detectable signal to be generated upon stimulation of the pathway, e.g., when a compound interacts with and modulates the activity of a cellular receptor or ion channel of the cell.
