Therefore i cooked some old potatoes | |||
I went to the Lab to make my own PDA-medium. To experiment more with mycelium and find out wich are the best conditions to grow it. Because i think for the paper production i need a lot more mycelium, i needs to be well moisture, for a stable growth, but nor to much medium, so that it can eat up the whole of it and i don´t have to dissolve the medium from the mycelium, because the water is not good for the mycelium either. | |||
Therefore i cooked some old potatoes, and boiled them for maybe 20 minutes, than took them out of the water. Weighed the Agar and the Dextrose, and added them to the Starch- brew. It burned a little on the ground of the pot, because the sugar can´t get too hot. | |||

I thought, now its proven: the closet is better than the oven! But Maike said, maybe the process in the oven is just fastened and the contamination sleeps in the closet-petridishes as well. So i decided to wait one more week. To see what happens. | I thought, now its proven: the closet is better than the oven!

One week later was the 28.12.17. I was in YMR for exactly 1 Day, and although i borrowed the key from Tseh, i couldn´t enter the BioLab because the whole building was closed and the Thoska didn´t work. | |||
