Bacteria interaction with painting
Goal: to combine drawings/paintings with bacteria
First try:
- Cluing the drawings on some stable underground, to prevent them from rolling when they are getting wet
- Cooking medium (source: Miga’s protocol)
- Glucose – 10 g
- Peptone – 2.5 g
- Yeast extract – 2.5 g
- Na2HPO4 – 1.35 g
- Citric acid – 0.75 g
- Distilled water – 500 ml
- Agar – 7.5 g
• Putting the medium on the drawings
• Putting them into a box
• After 3 days:
- -->Maybe the water with the nutrients was soaked into the paper
- -->Maybe there is no need for the agar in the medium, because the bacteria are growing good just on the paper (see second try)
• After 2.5 weeks:
Second try:
• Cooking the same medium but without agar
• Just putting the medium on some paper to see what happens without agar
• After 2.5 weeks:
- -->There was probably not enough liquid, so it did not really work without agar
Making different kind of media to create different kind of bacteria fields :
• I tried to to cook media with differen kind of acidity
- on the picture in the first petri dish there is the medium for the Growth of Gluconacetobacter but without citric acid
- in the second petri dish there is the standart medium for the growth of Gluconacetobacter, which includes some citric acid
- the third petri dish contains the medium for the growth of Gluconacetobacter, but with the double the amound of citric acid
Further steps:
- using thicker paper
- making the bacteria on the paper permanent, with maybe lack
- using different kind of media to create different kind of bacteria fields
