This invention is directed tomutants which produce a factor which potentiates the pesticidal activity of arelated pesticide, a chemical pesticide and/or a virus with pesticidal properties.

Mutants which produce a potentiator of bacillus pesticidal activity

The present invention relates to a factor that potentiates the pesticidal activity of a Bacillus related pesticide as well as methods for isolating and identifying said factor. The invention further relates to pesticidal compositions comprising the factor as well as methods of using the pesticidal compositions to control a pest and decrease the resistance of a pest to a pesticide and potentiate a Bacillus related pesticide.

Potentiator of Bacillus pesticidal activity

This invention is directed to Bacillus mutants which produce a factor which potentiates the pesticidal activity of a Bacillus related pesticide, a chemical pesticide and/or a virus with pesticidal properties.

Mutants which produce a potentiator of Bacillus pesticidal activity

This invention is directed to a method for obtaining a factor which potentiates the pesticidal activity of a Bacillus related pesticide, a chemical pesticide and/or a virus with pesticidal properties.

Methods for producing a potentiator of Bacillus pesticidal activity

Thermostable cyclodextrin glycosyl transferase and processes using it

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.

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.degree. C. The novel CGTases can be used for starch liquefaction at pH 4.5 and temperature exceeding 100.degree. 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.degree.-90.degree. 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.degree.-90.degree. C.
