Patents by Inventor Thomas E. Wall

Thomas E. Wall has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Culturing a microorganism in a medium with an elevated level of a carboxylate counterion source
    Patent number: 9187726
    Abstract: The invention provides a method of culturing a microorganism that produces a free fatty acid in a culture medium, comprising culturing the microorganism in the culture medium comprising a sufficient amount (e.g., at least about 0.5 mM) of a carboxylate counterion source to enhance viability of the microorganism in the culture medium. Fatty acids produced using the methods of the invention can be used to synthesize a variety of products, including biofuels.
    Type: Grant
    Filed: December 13, 2011
    Date of Patent: November 17, 2015
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Thomas E. Wall, You Chen, Stanley Bower, Wendy Loza
  • Production of fatty acids and fatty acid derivatives by recombinant microorganisms expressing polypeptides having lipolytic activity
    Patent number: 9175256
    Abstract: The invention provides transgenic photosynthetic microorganisms that include non-native genes encoding polypeptides having lipolytic activity for production of free fatty acids and fatty acid derivatives, and methods of producing free fatty acids and fatty acid derivatives using the transgenic microorganisms disclosed herein. The invention also provides transgenic microorganisms that include non-native genes encoding polypeptides having lipolytic activity, and novel genes encoding polypeptides demonstrating lipolytic activity.
