I received an example from Paola, because my Polycephalum wouldn't show up and grow. I also used something of her Potatoe-oat mix for agar plates. Paola experienced some pink stuff showing up in the dish after a while. But only with a few examples. The example she gave me is also doing the same. And it's somehow amazing. I did some reading and found out that everywhere PP moves it leaves slime traces full of chemicals. Mostly carbohydrates and sugars in it. This is an external spatial memory. It lets the organism remember where it already was in ordner not return back twice. In hour case thos tracks turn pink in the dish with the potato-oat mix.

So everywhere PP was he leaves now those colorful traces. But they also seem to disappear after a while, well at least the colour effect. Seems like this special plasmodium of the organism produces chemicals in its tracks that react with carbohydrates and protein proofing the existenz by showing a pink colouring. Like a chemical indicator. This is great in terms of observation. When you look after the organism after a few hours again, you'll be able to guess where it went. | ||

I took my new samples of polycephalum home again and they seem to like it better there. Its much more active at 19 degrees. I also tried a new medium with instant full grain oats, peptone, water and agar. Seems to work as well. But this time the pink stuff doesn't show up. I also noticed that even in the dish with the pink stuff, Polycephalum is not leaving those pink traces at all times. | |||

I also had another sample which seemed dead but I didn't throw it away. And only after one day it moulded completely and you could see Polycephalum on top of the mold mountains trying to escape it. I had a closer look with the microscope and could still see the plasmodial flow. | |||

==Pink Traces== | |||
The pink traces don't seem to be only some sort of chemical reaction. As I had a closer look with the microscope one could see its colonies of bacteria. I tried to do some researches on them in oder to know what they are and if they are pathogen or not. | |||
