Basic growth medium for bacteria
1. Goal:
- Can people without access to a professional laboratory grow microorganisms with ingredients that are available to everyone and cheaper than the extra-sterile components?
2. Procedure:
- The petri dishes are cleaned with a solution of 70% Alcohol + 30% of water (or destilled with a pressure cooker)
200 ml destilled water/ tapwater 3 ts sugar 2 ts bouillon/ peptone (proteins) 2 g agar (gellant)
We mixed different mediums, varying the ingredients: Mine contained distilled water, but instead of peptone I used bullion.
3. Outcome:
- Only the soil sample showed some result. Besides that we can only observe oil drops from the Boullion.
