Day 2 of your bacteriostatic/cidal experiment showed a hit for inhibiting growth, but the growth was increased as compared to day 1. In a compound that was certainly a bactericidal antibiotic, there would be very little absorbency change between the two days, but in a bacteriostatic compound, the absorbency of day 2 should look more like the negative control, which it did not. So do you think the compound was bacteriostatic or bactericidal and why?
Did you do any more serial dilutions to determine exactly where the drug stops inhibiting the growth of Salmonella typhimurium?
