Crime Scene
Suspect 1
Suspect 2
Suspect 3
Suspect 4
 Scientists
began to try to increase the
amount of penicillin produced by P. C.
bacteria, by irradiating it with X-rays and UV
rays in order to induce mutations of this
species. They succeeded and developed a
mutant that produced 1000 times the amount
of penicillin than Fleming’s original culture
