dttorun, if you're asking can you use a brine wash containing mycodore, I can tell you I did that with my first tomme. I used PLA, and mycodore, in a 3% brine. The only cautionary tale I'd offer came to me from Francois, who said to watch out for mycodore, as it can be fairly aggressive - its character can throw the overall effect out of balance (Francois, hope I remembered this more or less correctly).
