Song H. Bok 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).

  • Patent number: 5597835
    Abstract: A novel ACAT inhibitor of formula (I) useful for the treatment of hyperlipidemia produced from Aspergillus fumigatus FM-F-37; derivatives of said ACAT inhibitor, which are separated from the culture of A. fumigatus FM-F-37 or prepared by a chemical process, also possess ACAT inhibition property.
    Type: Grant
    Filed: October 7, 1994
    Date of Patent: January 28, 1997
    Assignee: Korea Institute of Science and Technology
    Inventors: Song H. Bok, Tae S. Jeong, Sung U. Kim, Byoung M. Kwon, Young K. Kim, Kwang H. Son, Hang W. Lee, Yong K. Kwon
  • Patent number: 5273749
    Abstract: The present invention provides an improved process for preparing coated microbial pesticides comprising antagonistic microorganisms and natural biopolymer originated from natural sources; and pesticides prepared therefrom.
    Type: Grant
    Filed: February 19, 1992
    Date of Patent: December 28, 1993
    Assignee: Korea Research Institute of Chemical Technology

  • Patent number: 5155041
    Abstract: The present invention provides a novel microorganism, Bacillus subtilis subspecies Krictiensis, and its mutant, Bacillus subtilis subspecies Krictiensis M 18-91; and a novel antifungal complex, KRF-001, produced from said microorganisms. The present invention also provides a process for producing said complex by culturing or fermenting said microorganisms and a process for purifying said complex to a desired degree of high purity.

  • Patent number: 4459354
    Abstract: Acidophilic and acidoduric streptomycetes strains have been found to produce carbohydrases. These Streptomyces effectively elaborate glucose isomerase under acid conditions typically unfavorable for growth of conventional glucose isomerase producing Streptomyces. Sterilization of the culture and production media may be avoided by selectively propagating newly discovered Streptomyces acidodurans under acidic conditions which will effectively eliminate contaminating micro-organisms. The Streptomyces acidodurans herein also have the ability to undergo cultivation and elaborate glucose isomerase over a relatively broad pH range. Constitutive streptomycetes strains have also been isolated. Glucose isomerases derived from these Streptomyces strains are particularly effective for isomerizing glucose syrups to fructose-containing syrups.
