  • Glycoengineered outer membrane vesicles and use thereof as vaccines
    Patent number: 9526775
    Abstract: The present application relates to glycoengineered outer membrane vesicles obtained from recombinant, gram-negative bacteria comprising hetereologous DNA encoding an enzyme or enzymes that produce a heterologous glycan that replaces all or a portion of the naturally-occurring O antigen in the lipopolysaccharides of the bacteria. Also provided by the present application are immunogenic compositions and vaccines prepared from the glycoengineered outer membrane vesicles expressing the heterologous glycans at their surface.
    Type: Grant
    Filed: April 26, 2013
    Date of Patent: December 27, 2016
    Assignee: WASHINGTON UNIVERSITY
    Inventors: Mario Feldman, Nancy Price, Fatima Garcia-Quintanilla, Maria Veronica Ielmini

  • High viscosity xanthan polymer preparations
    Patent number: 8034604
    Abstract: Increasing the molecular length of xanthan polymer makes a higher viscosity xanthan composition. Xanthan with higher specific viscosity characteristics provides more viscosity at equivalent concentration in food, industrial and oilfield applications. Methods for increasing the viscosity of xanthan include inducing particular key genes and increasing copy number of particular key genes.
