- Suppose you spilled two cultures of Salmonella typhimur-ium (each containing 100,000 cells) on your lab bench. You im-mediately applied the same disinfectant to both cultures at thesame time. One culture had been freshly grown for 36 hours andthe other culture is 2 weeks old. If the kill ing rate of the disin-fectant is 90% per minute, do you think that microbes in bothcultures will be completely killed after 6 minutes? Why or whynot?Bacterial capsule helps in adherence of bacteria to surface in its environment.
