With the new season of game of thrones upon us, I was motivated to draw the Stark sigil of a Dire wolf. I used E.coli since it appears dark on Eosin Methylene blue agar plate. I chose this media because it selects for E.coli to grow black, which contrasted nicely with the background. The media didnt change color.
As an avid fly fisherman and fly tier, I was motivated to use my own isolate strain in conjunction with an unknown white colony to produce a fly. I used TSA plate, which is not differential and did not change color, as the media to draw.
