It's easy to isolate from Kombucha, and some literature suggests this strain gives the best cellulose, too. :)
Just make up "Gluconobacter agar" (look it up on thelabrat.com) and streak your kombucha culture over it thinly. When I isolated it in this way, my colonies were brown, cleared the CaCO3 quickly, and in *late* culture, white crystals (of cellulose?) appeared around, but rarely atop, colonies.

Hi thereI am trying to produce nanocellulose and the cultures you can buy on websites like this one (https://www.dsmz.de/catalogues/details/culture/DSM-2325.html) are too expensive. I heard it is part of a microbe mix that is used to make some kind of asiatic tea beverage called Kombucha. Is it possible to isolate it from there?best regards,Phil
