Claim 1

A PROCESS FOR MODIFYING A PROTEINACEOUS MATERIAL BY THE BIOSYNTHESIS THEREIN OF GROWTH PROMOTING SUBSTANCES THAT COMPRISES SELECTING A LIQUID PROTEINACEOUS NUTRIENT MEDIUM; DISSOLVING IN THE MEDIUM SOLUBLE INORGANIC SALTS CONTAINING CALCIUM, POSPHORUS, AND NITROGEN; ADJUSTING THE INITIAL HYDROGEN ION CONCENTRATION OF THE MEDIUM TO WITHIN THE RANGE OF APPROXIMATELY PH 5.0 TP PH 5.5; INOCULATING THE MEDIUM WITH A YEAST OF THE SPECIES SACCHAROMYCES CEREVISIAE AND A CULTURE OF THE MICROORGANISM AEROBACTER CLOACAE; PROLIFERATING SAID YEAST AND MICROORGANISM SYMBIOTICALLY IN THE MEDIUM UNDER AEROBIC CONDITIONS WITH AGITATION AND AERATION AT A RATE OF APPROXIMATELY 50 TO 300 LITERS OF AIR PER 1000 LITERS OF MEDIUM PER MINUTE, WHILE MAINTAINING THE TEMPERATURE OF THE MEDIUM WITHIN THE RANGE OF APPROXIMATELY 26* C. TO 34* C., FOR A PERIOD OF APPROXIMATELY 24 TO 48 HOURS, UNTIL THE HYDROGEN ION CONCENTRATION OF THE MEDIUM LIES WITHIN THE RANGE OF APPROXIMATELY PH 7.5 TO PH 8.0; NEUTRALIZING EXCESS ALKALI IN THE MEDIUM BY ADDITION OF AN INORGANIC MINERAL ACID; AND DEHYDRATING THE SUBSTANTIALLY NEUTRAL BROTH TO OBTAIN A DRY SOLID PRODUCT.
