Which bacterial culture (Lb. plantarum, P. acidilactici, or P. pentosaceus) was most effective against monocytogenes and Salmonella? Explain why. What are the limitations of using an agar disk diffusion assay to assess the effectiveness of an antiseptic, disinfectant, or, in this case, a biological control agent on the growth of bacteria of interest?

Step 1
Bacteria are prokaryotic organisms that may be pathogenic in nature. The cells are devoid of cellular organelles like golgi bodies and endoplasmic reticulum. The bacterial cells lack a true nucleus, the one with a nuclear membrane. They reproduce by asexual reproduction, like budding. Antibiotic susceptibility refers to the condition in which the bacteria is susceptible to certain antibiotics.
