Types of Strain Deposits


Yeast strains can be deposited in NCYC. 

We currently accept 3 different types of Deposits:

  • Open Collection - Strains available to the public in the NCYC open database

  • Safe Deposit - Confidential yeast banking for companies

  • Patent Deposit - Protect your IP and deposit your strain/s to file a patent.



Preservation of  Deposited Cultures 

Upon receipt, the culture is checked for viability and purity. Yeasts are both freeze-dried and preserved in liquid nitrogen and viability is checked periodically in the same way as the main collection.



Strains are held at the Quadram Biosciences Institute with on-site security. A duplicate collection is also maintained on a geographically separate site as a further safeguard.
