The Challenge: Make an Antibacterial Cream



Now that we have grown the bacteria, how can they be destroyed?

Many modern antiseptics are based on natural plant products so it might be possible to extract a bactericidal cream from plants.

Plants with antiseptic properties often tend to be aromatic and produce an essential oil that inhibits bacterial growth.

How were the potential antiseptics tested?

Extracts of Yucca, Black Sage and Garlic were dropped on the plates where a 'lawn' of bacteria were growing.
