Deposit of biological material

Before sending strains, it is advisable to contact the related BCCM collection to make sure that the material to be deposited is within its scope and technical capability. The collection will also inform you of the necessary form and quantity of material to be deposited.

Public deposit

Make public deposit


What's in it for the depositor?

  • Preserve your materials off-site and for free

  • Promote scientific integrity by sharing your materials with researchers worldwide

  • Endorse open science, make your scientific work more visible and increase your citations

  • Focus on your core activities while the BCCM collections take care of the legal and administrative burden.

  • Comply with International laws for benefit sharing and Nagoya Protocol


Upon deposit, the depositor must complete the corresponding deposit form. A confirmation of deposit will be sent, in which the depositor will be informed of the accession number(s) assigned to the material.


Safe deposit


Make safe deposit

Resources in the safe deposit collection are not catalogued, and are only available to the depositor, or to third parties with the written authorization of the depositor.

The material is deposited for an undefined period, which can be terminated by the depositor each year up to one month before a next year starts.

Upon deposit, the depositor must complete the corresponding contract form.

See also the price lists.


Patent deposit


Make patent deposit

Since March 1, 1992, the BCCM consortium has been recognised as an "International Depositary Authority" (IDA) by the World Intellectual Property Organisation (WIPO).

Microbial resources deposited for patent purposes are not catalogued by BCCM. Samples can still be distributed however, upon written authorisation either by the depositor or an entitled Industrial Property Office, according to the rules of the Budapest Treaty.

Technical requirements for patent deposits

Bacteria, filamentous fungi, yeasts, actinomycetes

Please send:

  • 3 freeze-dried ampoules of the same batch;
  • 3 active cultures;
  • 3 cryopreserved ampoules of the same batch.


Arbuscular mycorrhizal fungi

Please send:

  • 2 in vitro (monoxenic) cultures of the same batch

If this is not possible,  send an "inoculum" containing propagules (i.e. spores and/or mycorrhizal root fragments) from an in vitro culture or from a trap plant, or a trap plant culture containing spores. It is mandatory that the "inoculum" is derived from a single monosporal culture. However, a mixture of propagules from more than one culture may also be accepted if the material is derived from the same mother monosporal culture.


Plasmids in a bacterial host

Please send:

  • 3 active, freeze-dried or frozen cultures of the same batch

One or more these cultures will be subjected to a viability test and subsequently serve for the preparation of a stock of cryopreserved cells.


Plasmids as isolated material

Please send:

  • 2 times minimum 20 µg plasmid DNA, in suspension, freeze-dried, frozen or precipitated in alcohol

The plasmid DNA must have a sufficient degree of purity to ensure successful transformation. The recommended bacterial host strain must be stated and - if not available at the depositary - also be furnished without the plasmid concerned. In the latter case, the storage of the appropriate host strain for the period of at least 30 years will be charged separately.

Human and animal cell lines, hybridomas

Please send:

  • minimum 12 frozen samples of the same batch containing at least 4 x 106 viable cells/vial

The animal and human cell cultures or hybridomas must be checked for contaminants before submitting. BCCM/GeneCorner may refuse the deposit when cultures are thawed upon arrival. Samples must be provided in well-sealed and clearly and durably marked 1-2 ml cryotubes of ± 12 mm diameter. One or more samples will be subjected to a viability test.

Budapest Treaty & Code of Practice for IDAs

To guarantee full disclosure of an invention involving microorganisms, the Budapest Treaty provides for the deposit of (micro)biological material with a recognised culture collection, known as an "International Depositary Authority (IDA)". An IDA must make the material publicly available at the appropriate point in the patenting procedure.

For more information see


Storage of third party’s biological material (STPM)


Make STPM deposit

The 'Storage of third party’s biological material' service offers the possibility to keep your most valuable resources safeguarded in a (supplementary), professional environment. The material will be stored without cultivation or manipulation, without quality control tests and without distribution, except to the depositor.

BCCM stores any biological material, that can be preserved at -80 °C or in liquid nitrogen.
