I'd want to know a lot more about that antibiotic these bacteria produce. If there is no natural immunity it will be developed very shortly if doses produced are low (and how can they possibly control for the dose). Then on the other hand if doses are really high, what about consuming an antibiotic for the rest of your life? What will it do to your gut flora? It seems very implausible to me. If I was working for FDA and someone was trying to bring such an obviously flawed product to the market I too would've asked them for very robust testing.
