  • Serveis

This is a special service for long-term preservation of microorganisms offered by CECT, in which their distribution needs expressed consent from the depositor and are not included in the public catalogue. All information concerning the deposit and the nature of the microorganism is treated in the strictest confidence.

CECT preserves the strain and ensures its viability whereas the depositor is responsible of its authenticity.

You can consult the Agreement for the deposit at the following link.

You can see the fees associated with this type of deposit in the fees section.

To check the authenticity of the preserved strain two vials will be sent and shipping costs will be included in the invoice (check fees).

Anyone interested in depositing strains in this way should be registered at the LIMS platform of the CECT and fill in the request Depósito restringido / Safe deposit,

Once the LIMS request has been accepted, to formalize a safe deposit, interested parties must:

  1. Fill in the on-line "deposit form" https://deposits.cect.org/login.php?locale=en_US (you can consult the tutorials website at: tutorials.strainsapp.org)
  2. Download the deposit form, electronically sing it and send it by e-mail to bacterias@cect.org or hongos@cect.org. If you do not have electronic signature, print the document, sign it and send it together with the cultures (step 3)
  3. Send two copies of a pure culture of the microorganism to be deposited

Please see the Guidelines for depositing strains in the CECT at our web page.

IMPORTANT: Review the Packaging Guide before shipping the samples. In all cases the outer packaging must be rigid (box or tube) and filled with packaging material (e.g. padding material or paper) to prevent movement of the samples inside the package.
