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
