This question was created from lab quiz 2 microbiology


1. Why did we test a chemical against several different types/species of bacteria
instead of just one type?
2. Why did we expose the bacteria to the chemical for different lengths of time-
what does this allow us to determine?
3. Be able to interpret the results of the plates that we used in the disinfectant lab to
determine (1) the effective exposure time (2) which chemical is best for
controlling a particular species of bacteria (3) which bacteria is the most resistant
(or the most vulnerable) to a certain chemical
