There are two types of scoby, lab grade & food grade. We made the lab grade in class, but I had used the previously made food grade for my mixture.
Lab grade: yeast extract, bacto-peptone, mannitol & distilled water.
Food grade: sugar, green tea bags, water.
So after we mixed up the medium we put it in the autoclave to sterilize the mixture. After cooling it down we could then pour the liquid (lab grade or food grade) into our desired container. The larger the container the longer the bacteria takes to grow. We then took already cultivated scoby and poured some of the liquid into our lab/food grade medium and we could have taken the scoby disc and placed it in our container as well. The disc speeds up growth, but it also leaves a circular dark mark and that may interfere with your design.
Essentially after this grows and does it's thing (not quite sure what that entails yet) it will form a thin sheet of "paper." The paper is similar to a vellum or parchment paper and can be dyed different colors if you add pigments to your lab/food grade medium.
We have to seal the container with mesh and tape all the edges securely to prevent fruit flies and keep it at room temperature for at least three weeks. So by sometime in the middle of June I will have this bacteria paper that I can print on or use to make something with. Hopefully...Because sometimes it can contaminate and grow mold. So let's hope I did it right!
After that workshop we had some free time because there was another safety orientation for metal today. So I got to chat with Suzanne Anker to figure what my project will consist of. I think it will consist of a lot of microscope photos and then complimenting those photos with 3D elements. She also saw some of my video work the other day and ordered these small Pico projectors for me to experiment with. There like 3"x6". I have an idea for them but still working it out. Also, she likes my appreciation for space and installation and showed me a separate room in the building that I could do an installation in as well as show work in my studio. So I gotta think of something for that as well, can't let that opportunity slip past.
