Control of Bacterial Growth

Learning Objectives:

Practice common methods of sterilization while exploring control of bacterial growth.


Students test radiation with respect to length of UV exposure versus UV effectiveness of controlling bacterial growth. They also test the UV blocking ability of different materials. A variety of disinfectants are tested by incubation with bacterial cultures. Finally, students sterilize bacteria in the autoclave and compare the level of growth to that of non-autoclaved bacteria.
