RS, a fully defined medium for growing diverse protists. RS medium is composed of two components: non-nutrient medium (NNM) and nutrient medium (NM). The NM component is diluted into the NNM component in order to achieve the desired concentration of nutrients in the final medium.
Non-Nutrient Medium (NNM) component, featuring a natural pH buffer system, is designed to mimic the chemical composition of seawater: MediaDive, https://mediadive.dsmz.de/medium/P4
Nutrient Medium (NM) component, with a wide variety of nutrients to support growth: MediaDive, https://mediadive.dsmz.de/medium/P5

Protist Cultures
We have strains in culture that we do not plan to pursue ourselves, but that might be useful to the community. Please contact us if you would like us to share them with you.
If you publish using one of these strains, we do not ask to be included in your publication, but we do ask you to agree to:
Deposit the strain in a public culture collection, on or before publication.
Make all data generated from the strain (sequences, assemblies, protein predictions, alignments, etc.) available in an appropriate public repository, on or before publication.
Publish a preprint and/or via open access, to ensure that anyone can read your work.
The list of strains in culture is available here, as a Google Sheet that we update regularly.
The majority of these cultures (indicated by BEAP IDs) contain more than one species of eukaryote (indicated by Within-Culture IDs: a, b, c, etc.). When two rows for a BEAP ID have the same Within-Culture ID, they represent forward and reverse 18S sequence reads that do not overlap.
Please note that we try to keep these cultures alive and growing, but there is always the chance that they may have died by the time you request them.
