Preparation
- 24 hour cultures of Staphylococcus aureus and Streptococcus pyogenes (enough for groups to share)
Materials
- 24 hour cultures of Staphylococcus aureus and Streptococcus pyogenes (enough for groups to share)
- new microscope slides (one per group)
- inoculating loops (one per group)
- hydrogen peroxide (enough for groups to share)
- transfer pipettes or droppers
The hydrogen peroxide cannot be old or have been exposed to light for prolonged periods of time. If this is the case, the reaction may not work. Be sure to use new or newer hydrogen peroxide in a light-proof container.
