Lactose fermentation and lactobacillus

[DReimerMT]

I was pondering the idea of making a sweet/milk stout but doing a little twist in the end, make it sour. I have made a milk stout before and I know that yeast will not digest lactose. I know that brettanomyces will digest lactose. My question is this if I add lactobacillus when the beer is racked to secondary fermentation will it digest the lactose sugars and give the sour taste I am looking for?

Probably not.

Once you have the alcohol and hops in there, the Lacto will be severely slowed down, if not stalled.

I believe Lacto will eat Lactose, in the right environment.

Brett does not convert Lactose.
