- 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?Why is it necessary to inoculate the KIA medium all the way down to the bottom of the tube during inoculation?How long does it take for E. coli to go from lag phase at time 0 to log phase to stationary phase to death phase? Can you point me to a citable source of this time period? I can't find anything online. Thank you.
