i looked at that and it looks like a very good product. i would definitely give it whirl. my only hesitation is that its pretty expensive and i wonder if you could extend it by cultivating few of the capsules? that would be an interesting experiment anyway.
please let us know how it goes with that product, i would be very interested in hearing anything about it, good or bad.
i do believe that the guy who developed that is keeping the specific species of bacteria in it a secret. its not even known in what country these bacteria came from, just that he found them in some remot jungle region.
