Microbial colors!

Uhm - yeah, that's not supposed to be there :-). A good reminder that even when you're working with all edible ingredients, you can't guarantee that what will grow on your plates will be safe. Likely a Penicillum spore, from the rotting lemons nearby

    Hi Sudharsan. We poured some DIY Petri plates using the "General Kitchen Agar" recipe described here: https://exploringtheinvisible.files.wordpress.com/2013/11/manual2013.pdf Then we inoculated the plates with some microbial species that we knew would be safe to work with: bakers' yeast, yoghurt, probiotic capsules, etc. We also played around with various colored plant extracts in the hopes to create some interesting chromogenic (color changing) media, but that had limited success in teh end (but was very pretty to work with!) More info in the pdf I linked to above, and at the event page for this meetup: http://www.meetup.com/Counter-Culture-Labs/events/146198362/ Patrik
