Abstract

The invention relates to Fusarium graminearum Schwabe deposited with the Commonwealth Mycological Institute and assigned the number IMI 145425 and variants and mutants thereof, as well as a culture medium containing the same.

Claims

1. Biologically pure fungal culture containing a strain of Fusarium graminearum Schwabe I.M.I. 145425 or a mutant or variant thereof in a culture medium in which this strain is present in a culture medium containing or being supplied with nutrients or additives necessary for the sustenance and multiplication of the strain, the medium having a pH between 3.5 and 7 and the temperature of the medium being maintained at a precise value within the range of between 25°

and 34°

C.

2. Biologically pure fungal culture containing a strain of Fusarium graminearum Schwabe I.M.I. 145425 or a mutant or variant thereof in a culture medium containing essentially growth-promoting nutrient substances, of which carbon in the form of assimilable carbohydrate constitutes the limited substrate in proliferation.

3. An article of manufacture comprising a biologically pure edible nontoxic fungal mycelium of a nontoxic strain of Fusarium possessing a high net protein utilization value of the order of 65 or above based on α

-amino nitrogen.

4. A biologically pure culture of the microorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI 145425, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprises an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.

5. A biologically pure culture of the microorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI 154209, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprises an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.

6. A biologically pure culture of the microorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI 154210, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprises an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.

7. A biologically pure culture of the microorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI154211, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprising an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.

8. A biologically pure culture of the micrrorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI 154212, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprises an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.

9. A biologically pure culture of the microorganism Fusarium graminearum Schwabe, having the identifying characteristics of IMI 154213, said culture being capable of producing proliferation of said microorganism in a recoverable quantity upon fermentation in a culture medium containing essentially growth-promoting nutrient substances, wherein said proliferated organism comprises an edible protein-containing substance possessing a high net protein utilization value of at least 65 based on the α

-amino nitrogen.
