Det er under normale omstændigheder nødvendigt at starte myceliet i et steriliseret medie. Dvs det er ikke nok at bruge et medie, der er behandlet med h202 eller pasteuriseret til at starte en kultur i fra sporer. Det koloniserede medie overføres så til fx pasteuriseret halm+hestegødning. H2o2 er mest til kloning, agar og lignende.
Det kan ikke dræbe de "endosporer" som er i feks rugkerner ("endo" = inde).
Nå for pokker! Jeg har ellers læst følgende:

The peroxide radical is a reactive form of oxygen which attacks various organic compounds. In
living cells, it damages the genetic material, cell membranes, and whatever else it finds to
react with. By doing so, peroxide in sufficient concentration can kill bacteria, bacterial
endospores, yeast, and spores of fungi, including mushroom spores. It apparently can also kill
small airborne particles of fungi, and the contaminants associated with human skin cells, which
are said to be continually flaking off of the mushroom cultivator. Hydrogen peroxide thus acts to
some extent against all commonly-encountered airborne contaminants of mushroom culture, including
mushroom spores themselves.
