Salvaging yeast from a Mexican Lager

[Alpha492]

I've never actually tried salvaging (or culturing don't know exactly what you would call it) but I was told it was possible, and the mexican lager yeast that I bought to make a Lime Cerveza Lager is apparently fairly rare. So I was wondering if it were possible to salvage this yeast to make another Lime Cerveza Lager, and if so how could I do it?

Ohh yea it can also be done from a bottle with yeast in the bottom like pac-man from rouge:fro:

There's no usable yeast in that beer. It's either micro filtered or pasteurized.
