Abstract: A microbial adherence inhibitor specific to lactic acid producing microorganisms, in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment or adherence of colony-forming immunogens in the fermentators. The inhibitor is made by inoculating female birds with the immunogen, allowing time for an immune response in the female bird and then harvesting the eggs that contain antibodies to the immunogen. The egg contents can be dried or used as a liquid and added to the media in the fermentators. Dependent upon the particular immunogen with which the female bird is inoculated, the egg antibody will specifically bind to the specific immunogen. When bacteria such as Lactobacillus spp. infect fermentation systems, they will further reduce alcohol conversion efficiency. Colony forming immunogens such as Lactobacillus spp.
