In this first try I started with cooking the standart medium out of Miga`s protocol. I also started with figuring out how the medium and bacteria are behaving on paper. Therefor I was cluing the some drawings on some stable underground, to prevent them from rolling, when they are getting wet | In this first try I started with cooking the standart medium out of Miga`s protocol.

After three day you can see, that the bacteria are growing more on the paper than on the medium, there is maybe no need for the agar in the medium because maybe the nutrients were soaked into the paper. (--> see second try without agar) | |||

It looks like there is probably not enough liquid, so it did not really work without agar and I went on with the standard medium and started to figure out how I can control the bacteria (see experiment further down) | It looks like there is probably not enough liquid, so it did not really work without agar and I went on with the standard medium and started to figure out how I can control the bacteria (see experiment further down) | ||

I also tried to put ink into the medium, so that it became blue. But after heating it up in the microwave the blue color disappeared. | |||
But still the bacteria were growing different than on the normal medium, somehow more intense, maybe because there is more bakteria inside with the added ink | But still the bacteria were growing different than on the normal medium, somehow more intense, maybe because there is more bakteria inside with the added ink | ||
