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

Second try:

• Cooking the same medium but without agar

• Just putting the medium on some paper to see what happens without agar

Further steps:

  1. using thicker paper
  2. making the bacteria on the paper permanent, with maybe lack
  3. using different kind of media to create different kind of bacteria fields
