Hello, I am looking for some deep-freezing advice/practical experience from a fungal expert: We are storing reference strains in our lab from bacteria and yeasts without problems, storing them at -80°C for long time storage (w/ glycerol). Now we also need to have a Aspergillus brasiliensis on stock for our reference checks. We know that molds are often treated differently in regards to freeze storage - is there anyone who can advise us about how to treat this strain so that we can deep-freeze and reactivate it succesfully for 1-2yrs of storage? Thank you in advance, Erik
