  • Method for enhancing production polyhydroxyalkanoic acid from microorganism strains
    Patent number: 8685700
    Abstract: Provided is a method for enhancing the production of polyhydroxyalkanoic acid (PHA) from microorganism strains by disrupting a gene associated with the production of an exobiopolymer (EBP) in the Pseudomonas strain to redirect the carbon flux toward the production of the polyhydroxyalkanoic acid, thereby enhancing the production of the polyhydroxyalkanoic acid.
    Type: Grant
    Filed: April 23, 2010
    Date of Patent: April 1, 2014
    Assignee: Industry-Academic Cooperation Foundation Gyeongsang National University
    Inventors: Sung Chul Yoon, Ju Xu, Mun Hwan Choi
  • Method for producing polyhydroxyalkanoic acid
    Patent number: 8658403
    Abstract: Provided is a method for producing a polyhydroxyalkanoic acid (PHA). More particularly, a method of preparing PHA containing a high content of long-chain aromatic monomer-units by growing a phaZ mutant of a Pseudomonas strain in a medium containing a sugar, a substituted fatty acid, and a salicylic acid.
