Bacteria in petri dishes

this is so cool! :)

They are really beautiful. I kind of want to crochet them as doily designs.

These would make awesome pins.

These would be amazing pins.

I thought these were just really awesome icing decorations...

As a microbiology major, I can tell you now that this is inaccurate and stupid because the only way to get those combination of colours on a single Petri dish would be to stain bacteria different colours and mix them up. So essentially you're just looking at die for the purposes of pretty colours. Bacteria very rarely come in these majestic colours
