Note: for strains where we have DNA barcodes we can be reasonably confident of identity, however for those not yet sequenced we rely on morphology and the original identification, usually made by the depositor. Although CCAP makes every effort to ensure the correct taxonomic identity of strains, we cannot guarantee that a strain is correctly identified at the species, genus or class levels. On this basis users are responsible for confirming the identity of the strain(s) they receive from us on arrival before starting experiments.
For strain taxonomy we generally use AlgaeBase for algae and Adl et al. (2019) for protists.
