scoby growing in vinegar- what can I use it for?

I make cleaning vinegar, putting citrus rinds in purchased white vinegar (normal stuff, i don't have the bottle but I assume around 3 or 4% acidity). I put it in a jar and throw it under the sink for 6 months or so.

I found the jar today and it has a beautiful snow-white scoby on top (much prettier than my kombucha scobies ever got). This is not the mother of vinegar from making vinegar (I have that too), this is def a scoby.
I also happen to have a jar of kombucha with a dead scoby (or very sad, I haven't tried to rescuscitate it yet. It may have died from neglect, don't call the booch police on me.).

Can I take this scoby and try to use it with booch? Or is there something better to do with it?
The citrus was almost certainly unwashed and local, I can recognize some of the lemons from my aunt's yard, so I am assuming it's got a good contingent of yeasts.
Thanks!

three weeks later, i used it to get a pot of kombucha going. I am starting to realize i have a bit of a yeast imbalance in my other kombucha, and the difference between the two is fabulous. (now to keep that yeast down, going into summer)

Ha! I just got the same. I have been noticing little bits forming and blocking the tube on the spray bottle, but yesterday I saw a beautiful white scoby at the bottom of the bottle.
What is it good for?
