1st class: 16. Oktober 2018 - Introduction
Summary
General introduction to working in the bio lab. Preparing the first testing Agar-Plates for bacterial growth in a petri dish:
- petri dishes where filled with 15 ml of an LBP (Baird-Parker liquid) Medium with Agar Agar
- cooling down
- inoculateing with different surface smear
- In my case: human nose (inside), cat nose (outside) and fur, fridge glass surface and 1 cent coin
- left with room temperature for the following days
First culture medium
As described obove the filled petri dishes are no beeing observed for the following days.

Breeding day 7 - closer look
Somehow I got the impression that the petri dishes weren't sterile as after 7 days almost the full dish is covered with a white film. You can only guess by slightly different colors where I initially inoculated the dish. Something seems to grow over the originally inoculated sections. See below some close ups. In the section of the example I took from my nose, a small yellow dot appears. I think this is what was intended to be growing. The rest just looks almost the same.
