Re: [DIYbio] Re: Food Safe Bioluminecence?

Really nice info, thanks to all for sharing! I'm definitely interested in making glowing kombucha and other brews/foods mostly for "presentational/promotional purposes". I've been brewing for many years with kombucha culture and last year I've started to play with the microcellulose biofilm produced by the SCOBY. I've to put it on halt but some of the results were quite good, my hope was actually to use it in a way as a insulator around 5 V circuits - I hope to use it in our Experimental Incubator which next prototype (without this feature alas) we will present at 31c3 in Hamburg. My favorite way to make the kombucha glowing would be to introduce into the culture some "natural" microbe which would actually "demestify" and live there producing what ever type of bioluminiscence/fluorescence possible and still be food safe.

Anyway nice info especially the last link to the Bruce Bryan's work!

Sincerely,

FAA

Ha! Do you have a link for the luciferin being used as a food flavoring? Sounds interesting. Found this doing a quick search: http://blog.khymos.org/2009/02/11/the-flemish-primitives-glowing-lollipops-part-4/ <--Are they all unknowingly test subjects? LOL

..in case that sounded like a suggestion that eating Vibrio spp is safe, please disregard. I'm only referring to the luciferin pathway. Even the Vibrios that aren't virulent are usually quite toxic.

I was about to mention something about fireflies. A while ago I really wanted to make some kind of bioluminescent beer, or kombucha, if the alcohol was too strong in beer. I looked into fireflies for a while but it looked like they may be toxic - but I have no idea if this is related to the bioluminescence pathway or is separate. I believe it is related to a groups of steroids lucibufagins. Though I don't know if they're present in all species of fireflies or just a few.

Yeah, I agree - stick with fluorescence rather than bioluminescence! A lot more light production, and a lot more edible choices!

I don't know of any bioluminescent organisms that are known to be actually edible. I know some of the bioluminescent fungi are toxic. And although some (not all!) of the bioluminescent Vibrio are non-pathogenic, I definitely wouldn't want to eat them. If you're determined, I would think that fireflies may be your best bet for a bioluminescent organism that could potentially be edible. But that's just a guess, based on the fact that many insects are edible...

Fluorescent and edible - here you have tons of choices! Tonic water (quinine), turmeric, A and B vitamins, chlorophyll, etc...

Broke out the conversation...

You can also go for fluorescence... tonic water fluoresces under uv light.
For most bio luminescence it has to be very dark to start with.
Start thinking about a space where you can't see your hand in front of
your face.  (think about this before "whether it is safe to eat")
