5.18 Core Practical - Investigating the Effects of Antiseptics and Antibiotics and 5.19 Calculations with Bacterial Cultures
Intro
If we apply an antibiotic to the agar plate, this is a useful calculation - as it allows us to determine the effectiveness of the antibiotic
In Part 1 of this experiment, we will grow the bacterial culture, and in Part 2 we will use πr2 to examine how effective the antibiotic is
It is possible to calculate the cross sectional area of a bacterial culture using the formula for the area of a circle

We can repeat these calculations for multiple antibiotics and bacteria, in order to determine the effectiveness of different bacteria/antibiotic combinations. This is useful as it allows doctors and scientists to work out which antibiotics are most effective for particular bacterial infections
