Yes, like Kevin, I have only seen the organism for sale.  You spray in on crops typically attacked by caterpillars, the caterpillars eat the bacteria, the organism grows producing a toxin, the caterpillar stops eating within 24 hours and dies, leaving behind a corpse well laden with more of the Bt bacteria to continue the cycle.  That's one of the really weird things about Bt corn, that it's a whole field full of plants producing Bt toxin, instead of a few caterpillars scattered here and there.  No one knows what all that Bt toxin can do.   Donna
