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.

Culture media, purity and growth conditions:

Attributes
AuthorityHassall 1850
IsolatorJaworski (1979)
Collection Site Esthwaite Water, Cumbria, England, UK
Climatic Zone Temperate
Notes Isolation: micropipetting and dilution; The characteristic way in which diatoms reproduce asexually results, in some strains, in the reduction in size of diatom cells at every division and the subsequent loss of morphological characters. This strain has shrunk slightly but still forms star and half-star formations.
