  • Patent number: 6184001
    Abstract: Novel cyclodextrin glycosyl transferases (CGTase) can be produced by anaerobic cultivation of strains of Thermoanaerobacter or Thermoanaerobium. They are more thermostable than known CGTases and have temperature optimum about 95° C. The novel CGTases can be used for starch liquefaction at pH 4.5 and temperature exceeding 100° C. in the production of dextrose or ethanol. They can also be used for conversion of liquefied starch to cyclodextrin at a temperature of 80-90° C. A method for enzymatically converting solid and liquefied starch into cyclodextrin using cyclodextrin glycosyl transferases (CGTase) elaborated by thermophilic obligate anaerobic strains belonging to the genus Clostridium. These CGTases are characterized by thermostability and a capability to liquefy starch and/or to convert liquefied starch to cyclodextrin at pH 5.0-5.5 and 60-90° C.

  • Patent number: 5976563
    Abstract: The invention is related to a novel strain(s) of Bacillus thuringiensis in which essentially all of the pesticidal activity of said strain is in the supernatant of a fermentation of said strain. The strain produces a substance which has activity against an insect pest(s) of the order Coleoptera and which enhances the pesticidal activity of a Bacillus related pesticide. The invention further relates to pesticidal compositions comprising the substance and a pesticidal carrier, or the substance and a Bacillus related pesticide, a chemical pesticide and/or a virus with pesticidal properties as well as methods of using the pesticidal compositions to control a pest.
    Type: Grant
    Filed: October 8, 1997
    Date of Patent: November 2, 1999
    Assignee: Abbott Laboratories
