CCUG Deposit Policy

Depositors – Before sending strains, please contact the CCUG Curator ( or the CCUG Lab ( to confirm that the Collection is able to accept your deposit.

The CCUG accepts depositions of bacteria and some yeast and fungi of interest for the scientific community. The mandate of the CCUG is to provide as comprehensive as possible archive for reference strains of medically- and clinically-relevant microorganisms. Additionally, the CCUG is happy to accept deposits of reference strains for biodiversity, biotechnological, industrial, food and environmental microbiology applications and research. No fee is charged for deposits of the Type strains of newly described species and other well-characterized reference strains.

The policy of the CCUG for accepting proposed Type strains of novel species is friendly and simple:
After confirmation from the CCUG Curator or the CCUG Lab, send the strains for deposit with the accompanying CCUG Deposit Form, filled out with as much information as possible. Please note the fields in the CCUG Deposit Form marked with a ‘*’; this denotes information that is required for deposition of strains with the CCUG. Information on manuscripts or copies of manuscripts completed or in unfinished state, describing the strains is helpful and appreciated. All information sent to the CCUG will be maintained in confidence.

The CCUG recommends that deposits of proposed Type strains of novel species be made shortly (1 to 2 months) before submission of a manuscript to the International Journal of Systematic and Evolutionary Microbiology . Unique CCUG accession numbers are assigned to deposited strains. Depositors receive information on CCUG accession numbers after the strains have been lyophilized and Quality Control of viability and purity is completed (2 to 8 weeks, depending upon the cultivation nature of the microorganisms). Two batches always are prepared for the very fastidious strains and the accession numbers will be available only after the second batch is completed; thus, for some strictly anaerobic or microaerophilic microorganisms, several weeks may be needed.
