Mykos water soluble powder in compost teas?

Most of the soluble mycorhizal products say to agitate in water for several minutes and then apply, I think it is because the mycorhizae need living roots to survive so you just want the spores/propogules awakened and then put into a root zone. I think that the fungi cultivated in aerated compost tea are just general soil fungi that live freely eating on soil detritus. Even they have a hard time propagating in actively aerated compost teas as the agitation breaks hyphae easily. I've been told.that fungal vigor peaks at about 18 hours in a simple bubbler set up, maybe a bit different of using a vortex or some other system.
