After notifying people of this someone pointed out that this makes a "plant", but not S.f&Laco (a scoby)
*so this was my reply as part of this thread

"Yes, a GBP is specifically Saccharomyces florentinus and Lactobacillus.
When I first heard of GBP years and years ago I was taught/learned that S.florentinus naturally occurs in ginger root, and the bacteria Lacto is also just naturally occurring in most homes and the fermenting ginger and sugar gives rise to the yeast which is then a perfect environment for the bacteria to set in via being exposed to the open air.Over time it develops into a scoby.
HOWEVER, I've spent like 4 hrs straight and yet to find anything that proves OR disproves this idea! I can't find any info on where S.f actually comes from, or it's origin. I read several places that state the GBP's original origin is actually UNKNOWN(?). All the research I can find only talks about what it is, how it works, what it does, and how to take care of it, but never where it comes from, other than saying in ginger water. According to the internet, it only exists in yeast banks, or people's kitchens, but it must live somewhere in nature, and have a origin. Everything else is everyone stating that certain strains are fake, or not the real GBP, etc.
So now Im quite perplexed.... Anyone have information on this???
For now, I will continue to mature this plant. It smells exactly like a GBP that I smelled in the past, (at least from memory) and it is supposed to form a gelatinous mass as well. Then make a brew to see what the outcome is, and report back."
