Mozz storage...?

[muffinmu]

An Italian frien of ours makes Naples style pizza in his woodfire oven, as a business...he buys his fresh Mozzerella in buckets, and the cheese is stored in liquid...what I need to know, is if the mozz I make in small lots with my microwave, can be stored this way, what the liquid would be, and how long it will keep?
Thank you!
