That is a phenomenal question!

I have also noticed the ability for cyanescens and azurescens to eat mold like it was candy. It makes them so nice to work with!

If a person could devise a strain of cubes with this power, they'd really be on to something.

One thing to keep in mind, that the common use of "trich" often is used over a wide variety of molds, some of which aren't actually trich. So, the problem may be complex in that the cube might only eat certain types, but not others.

Another idea might be to develop a strain that was more hearty in less favorable conditions. If a cube could grow and abundantly fruit in say 60-65 degrees F, and 75% humidity, I think the risk of mold would be greatly diminished. That may prove harder than growing a trich-eating strain, though.
