Production of edible protein substances
First Claim
1. A process for the production of an edible protein-containing substance which comprises incubating and proliferating, under aerobic conditions, a non-toxic strain of the genus Fusarium or a variant or mutant thereof in a culture medium containing all essential growth-promoting nutrient substances, of which carbon in the form of assimilable carbohydrate constitutes the limiting substrate in proliferation, and separating the proliferated organism comprising the edible protein-containing substance possessing a high net protein utilization value of at least 70 based on the α
- -amino nitrogen.

Abstract
Process for the production of an edible protein-containing substance which comprises incubating and proliferating, under aerobic conditions, a non-toxic strain of the gensus Fusarium or a variant or mutant thereof, in a culture medium containing essential growth-promoting nutrient substances, of which carbon in the form of assimilable carbohydrate constitutes the limiting substrate in proliferation, and separating the proliferated organism comprising the edible protein-containing substance. Novel strains and variants of Fusarium graminearum are also disclosed.
