摘要： ALPHA AMYLASE CAN BE PRODUCED BY FERMENTING, UNDER AEROBIC CONDITIONS, NUTRIENT MEDIA CONTAINING AT LEAST A PORTION OF FOWL EXCREMENT. THE FERMENTATION IS ACCOMPLISHED BY MEANS OF MICROORGANISMS SELECTED FROM THE GROUP CONSISTING OF THOSE PSEUDOMONAS, CORYNEBACTERIA, CELLUMONAS, BACILLUS, ASPERGILLUS AND CANDIDA CAPABLE OF PRODUCING ALPHA AMYLASE BY METABOLIZING FOWL EXCREMENT AS A SOURCE OF ASSIMILABLE CARBON AND/OR A SOURCE OF ASSIMILABLE NITROGEN. PARTICULARLY GOOD PRODUCTION IS OBTAINED BY USING FIVE NEWLY DISCOVERED STRAINS, BACILLUS CEREUS A.T.C.C. NO. 21768, BACILLUS CEREUS A.T.C.C. NO. 21769, BACILLUS CEREUS A.T.C.C. NO. 2170, BACILLUS CEREUS A.T.C.C. NO. 21771, BACILLUS CEREUS A.T.C.C. NO. 21772. WHEAT CHAFF IS AN EXCEPTIONALLY USEFUL NUTRIENT INGREDIENT AND GLYCINE IS A PARTICULARLY EFFECTIVE STIMULANT FOR SOME OF THESE PROCESSES.
