Preparations for sample preparation

Pour agar plates, label & prepare for sample preparation

Today, the students of the Model School Graz have prepared the nutrient media with the help of Tobija Glawogger (TUG Graz, Environmental Biotechnology).
For this they mixed and sterilized nutrients with agar. The resulting solution was still hot in the sterile bench (pure workbench) poured into sterile Petri dishes where it solidifies.
Later, these finished agar plates are used to grow the bacteria from the apple.
Then they cut off the ends of the pipette tips.
These are sterilized and later used to pipet the thick apple pulp onto the agar plates.
