Karuna Ponniah Karunakaran 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).

  • Mutant Strains of Pseudomonas Fluorescens And Variants Thereof, Methods For Their Production, And Uses Thereof In Alginate Production
    Publication number: 20100323408
    Abstract: It is described biologically pure bacterial cultures of mutant strains of Pseudomonas fluorescens, which produces large amounts of alginate. The alginate may contain a certain determined content of mannuronate and guluronate residues, possible presence and determined level of acetyl groups in the alginate, and a desired molecular weight of the alginate. Also high yielding mutants with regulation of alginate production, is described. The invention further provides methods for producing new mutant strains of Pseudomonas fluorescens and variants thereof, and use of the resulting strains in alginate production.
    Type: Application
    Filed: May 19, 2009
    Publication date: December 23, 2010
    Applicant: FMC Biopolymer AS
