A major repository of Chlamydomonas cultures, especially for mutants and other strains frequently used in research, is at the Chlamydomonas Genetics Center at Duke University. Information on the strains maintained at the Chlamydomonas Genetics Center is available via The Chlamydomonas Database ("ChlamyDB"). ChlamyDB also keeps a database of strains from other collections.

Many strains, including practically all used in research involving genetics, are axenic and sexually competent. Cultivation on liquid or solid media in the light is generally easy, and some strains will grow well in the dark as heterotrophs.
