Bacillus Coagulans selective media?

So GTs has Bacillus Coagulans and Saccaromyces Boulardii in it, and I want to selectively culture the BC - does anyone know if BC can eat Maltodextrin? I use a maltodextrin starter to culture Brett out of beers that have both Brett and Sacc in them. I'm not too concerned about getting a pure culture here, just want to get a good population of B. Coagulans to pitch. When I've tried making a straight starter I seem to get mostly S. Boulardii/yeast, so I'm trying to select for more BC production.

Any suggestions are welcome, Thanks guys
