Abstract:
Investigate the effectiveness of antimicrobial agents on the growth of a bacterial lawn.
Hints & Tips:
- Growing bacteria in anaerobic conditions will favour the growth of anaerobic bacteria. To avoid this use vented Petri dishes and only secure with tape following incubation.
- Following incubation learners must not remove the lids to the Petri dishes.
- Advise students not to seal the lid all the way around as this creates anaerobic conditions.
- 1% Virkon solution is particularly effective for swabbing benches before and after practical work.
