Every year, UTEX accessions new algal strains from depositors that are made available to the public.

If a strain fulfills the Criteria for Accession of New Algal Strains Into the UTEX Collection & Taxonomic Considerations for Algal Cultures, depositors should download and submit a Public Strain Accessioning/Deposition request form. No strain should be sent for possible accession into the Collection without prior approval by the Curator. If you are interested in depositing a strain that would be available exclusively to the depositor, please visit the Proprietary Strain Deposition page.
