The time required to regrow this culture, prior shipping, is approximately 22 days. If interested, please contact the CCMP for the cryopreservation methods (freezing and/or thawing protocols).
Note that aquaculture strains are always maintained as actively growing cultures, even if also cryogenically stored. Therefore, aquaculture strains (see aquaculture express ordering on the CCMP home page) can be shipped immediately upon request.
