What kind of treatment you use with fungicide and do you test for residues of it?
The mycelium is mixed with an extraction buffer. Our effective component in the mycelium extraction is phenol, in a concentration of 1 %. We mix the buffer with the mycelium and filtrate this with our last filter is a 0.45 µm filter. We dialysed the filtrated liquid with a volatile buffer, so after freeze drying a minimum amount of salts is available. With this you can use every buffer you prefer in reconstitution the freeze dried product.
