Im not sure you had the right strain of mold. Try the penicillin G (benzylpenicillin) strand, it also has three stages of biosynthesis and the necessary aminos etc. (which I doubt the bread contained the proper), sounds like you you only attempted one stage of underthebedysis. Funny that you brought that up, it is like algae in a way, that they both require certain conditions, certain amino's etc. to be correct. I am confident that BEHL has figured out how to "grow algae", I think at this point it has come to how quickly and cost efficient they can do this.
