Sarah Brower (F02) Painting with Microbes

Spring (This is turned, the MAC should be on the top of the picture.)

I tried to make a cherry blossom tree branch using  Chromobacterium violaceum for the bark and  Serratia  marcescens for the flowers and petals.   Both of these microbes are fermenters, I wanted the petals to slowly leach out the pink of the MAC agar.

I wanted to give a bit of contrast with the petals and the background, so I chose the MAC agar for the color change and S. marcescens for that property and for the color of the bacteria.
