How to culture Lactobaccillus

[Newsman]

I'm looking to brew a BerlinerWeisse, and the recipe calls for Lacto, both naturally-occurring and cultured. I presume when one "cultures" lacto, you make a starter like you would with regular brewer's yeast. If not, how does one "culture" a commercial strain of Lacto?

Fresh apple juice and heat belt @110F for a few days.

I mean fresh pasteurized apple juice.

Nifty. Thanks. I'll give that a shot when I get my commercial culture from the LHBS. I don't know when they're going to order it, but I really want to make the Georgia Airlift clone I posted the recipe for.

I used some second runnings with a little unpasturized apple juice and a small handful of grain in a container then put it in a crock pot on the warm setting for a couple days. Very sour!
