CCMP1316 was cryopreserved on Apr 30 1999 using 10% DMSO as a cryoprotectant.
The time required to regrow this culture, prior shipping, is approximately 21 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 strain starter cultures (2x15ml) and only starter cultures can be shipped within 24h of ordering (see aquaculture express ordering on the CCMP home page) .
New daughter set created every four weeks
Daughter set……….…50umol quanta m-2 s-1
Mother set………….…16umol quanta m-2 s-1
Grandmother set….….16umol quanta m-2 s-1
Q+A:
Q: I was looking to order CCMP1316 and was wondering if there are any significant differences between the start culture and 1L mass culture (density, level of sterility, etc)?
A: The only difference is in the ship time. Starter cultures are ~2 weeks, 1L cultures may take a couple weeks more.
Q:And do you still have these cultures at a salinity around 32ppt?
A:Yes, our marine cultures are at ~32ppt.
