Looks promising and bacterial controls are the future IMHO. That said I will add that I have had great success eliminating mold and mildew with potassium bicarbonate which is very cheap and for me solved my PM and BM issues in 2 treatments.
Edit: I see Monterey has it for 16 bucks, for that price I'm down for trying it.
