Abstract

The efficiency of an anaerobic probiotic bacterium against bacteria that cause food deterioration was tested in the current investigation. Based on our prior research, Bifidobacterium bifidum was chosen as an anaerobic probiotic bacterium. By using the conventional method of isolation, food spoilage bacteria were isolated, and through biochemical and molecular characterization, isolates of Escherichia coli, Staphylococcus aureus, Shigella dysenteriae, and Salmonella typhi were detected. Bifidobacterium bifidum demonstrated strong inhibitory capacity against all identified food spoilage bacteria in the agar well diffusion method, with the exception of Shigella dysenteriae.
