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:
Medium: West McBride Medium; Bacteria and other organisms present; maintained by serial subculture and cryopreserved;
Attributes
IsolatorBlouin & Brawley (2008)
Collection Siteexposed shore, mid-intertidal zone Blueberry Hill, Schoodic Point, Maine (Acadia National Park) USA
Notes Isolation: microscopic isolation of blade area free of endophytes, with use of GeO2 and Pen-Strep antibiotics; Reacquired from S Brawley November 2017; Material grows best with bubbling of medium to simulate intertidal habitat; also, after a diameter of about 4 cm is reached, the material grows best if it is not tumbled but is positioned (e.g., with an aquarium store "seaweed clip" by its rhizoid so that natural polarity is maintained. If tumbled at larger size, the margin of the blade tends to fold over, neutral spores germinate in place and it isn't pretty. Material will also be fine in flasks on a shaker; This macroalgal culture contains bacteria and probably other organisms in low numbers, we are happy to provide further info on specific strains if you contact us 10 C is best for growth, but it is fine from 5-12 C; P.um.1 grows at 15 C, but as temperature approaches 20 C, growth slows and red color is hard to maintain.
