Strain deposition


The CCALA collection accepts cyanobacterial and algae cultures especially associated with taxonomic research (reference strains for new genus and species), cultures from interesting habitats or strains with biotechnological potencial. 

If you are interested in depositing the cultures, it is advisable to arrange in advance with the curator of the collection - Mgr. Josef Juráň, Ph.D. ( 

The deposited culture must meet the following rules:

1. Cyanobacteria and algae cultures correspond to the following requirements may be deposited to the CCALA collection:

a. the material will be physically delivered to the collection;

b. the cultures will be unialgal1;

c. the cultures will be axenic2 or xenic3;

d. in the case of xenic cultures, only a small amount of bacterial contamination is possible; in special cases (at the decision of the curator) cultures contaminated with small amounts of filamentous fungi may be accepted; culturers contaminated by protozoa will not be accepted into the collection or will be rejected during quarantine;

e. the deposited material will be accompanied by a signed deposit protocol (download here), or other necessary documentation;

f. the deposited material will correspond the conditions set out in the Nagoya Protocol (see point 3).

2. If the culture contains a genetically modified organism4, its deposition must be discussed with the curator in advance.

3. A strain could be deposited in the CCALA collection if it correspond at least one of the following conditions related to the implementation of the Nagoya Protocol5

a. was acquired before 12th October 2014;

b. originates in a country which is not a signatory of  the Nagoya Protocol;

c. originates in a country which is a signatory to the Nagoya Protocol but does not regulate access to its genetic resources;

d. was obtained after 2014 in one of the countries that are signatories to the Nagoya Protocol and regulate access to their genetic resources, but it is with complete required documentation.

4. If the conditions (points 1 and 3) are met, the deposited strain will receive an unofficial collection number and will be kept in quarantine mode for at least 3 months.

5. After the quarantine, the strain will be checked and if it meets the above-mentioned material quality conditions (points 1b. - 1d.), It will be included in the collection assortment under the official number.

6. In case of keeping the strain in the private (non-public) part of the collection is this service is charged according to the valid price list of the CCALA collection.

7. The collection reserves the right not to accept deposited strains that do not meet some conditions listed above (points 1 and 3) or discard and transmit material during the quarantine period and return them to the depositor no later than 6 months after the physical delivery of the material to the collection.
