Growing Physarum Polycephalum

Medium: 100ml water 3g agar Cooked Directly in a flask on the stove until boiling point, while consistently mixing. The flask and the large petri dish were both sterilized in the UV chamber for approx. 20 minutes.

Sample: The Physarum Polycephalum was taken from healthy dried samples, on a paper and a paper towel.

Food source: Dried Oats (not sterilized)

Conditions: - 20 degrees temperature - enough moisture (introduced in the initial cultivation) - kept in a dark environment

Follow-up on the above Physarum Polycephalum sample in the large Petri dish

Results: The above sample was unsuccessful. Potential causes: Clear contamination which might be the result of using unsterile oats, and paper/paper towel samples.
