Claims

1. A PROCESS FOR THE MICROBIOLOGICAL PRODUCTION OF PROTEIN WHICH COMPRISES THE STEPS OF (I) AEROBICALLY CULTURING A SPECIES OF FUNGUS OF THE CLASS FUNGI IMPERFECTI (DEUTEROMYCETES) WHICH IS NON-PATHOGENIC TO HUMANS IN AN AQUEOUS MEDIUM UNDER CONDITIONS WHICH SUPPORT GROWTH OF THE FUNGUS, SAID CULTURE INCLUDING THE FOLLOWING:

(1) A SOURCE OF ASSIMILABLE CARBOHYDRATE, (2) A NITROGEN SOURCE SELECTED FROM THE GROUP CONSISTING OF (A) A WATER-SOLUBLE INORGANIC NITROGEN SOURCE AND (B) A NON-PROTEIN ORGANIC NITROGEN SOURCE, AND (3) A ZINC SALT IN AMOUNT BETWEEN ABOUT THIRTY PARTS PER MILLION BY WEIGHT OF THE MEDIUM AND THAT AMOUNT WHICH INHIBITS GROWTH OF THE FUNGUS, AND (II) SEPARATING THE PROTEIN-CONTAINING FUNGAL TISSUE FROM THE CULTURE MEDIUM.
