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.

Isolator | Küpper & Müller (1996) |
Collection Site | infecting epiphytic Pylaiella littoralis on Ascophyllum nodosum Aith Voe, Bressay, Shetland, UK |
Climatic Zone | Temperate |
Notes | Isolation: see Müller, Küpper & Küpper 1999. This is an unialgal host culture - Eurychasma (an oomycete parasite of brown algae) is an obligate biotroph, i.e. it cannot grow outside its host. The host in which this strain was deposited is Pylaiella littoralis (Pyl IR / CCAP 1330/3); it is now maintained in host Macrocystis pyrifera CCAP 1323/1; Transfer into new medium twice monthly, with addition of some healthy host to ensure the propagation of the infection. Algal cultures used for Eurychasma inoculation must have been grown for 2-3 weeks in liquid medium. |
