During a color workshop a few weeks ago, we tried our hand at putting Janthinobacterium lividum on cloth. It became red, for some reason. And it didn’t grow very well either. The culture came straight out of the glyc stock, maybe that’s why the growth was stunted?
We soaked the cloth in Nutrient Broth:
Yeast extract 2.0g
Demi water up to 1000 mL
