Notes: |
this is a marine isolate growing in freshwater medium; 1976 renamed (George 1976); high EPA/lipid content (Yongmanitchae & Ward 1991); (Lewin 1958, Lewin & Lewin 1960); In 1974, J.C. Lewin (pers. Comm.) identified some of our Nitzchia cultures as Phaeodactylum [see UTEX 640, 642, 646 & 2089] with the following explanation: "Oval cells of Phaeodactylum occur in cultures kept on agar. There is a gradual transformation back to the fusiform state, after oval cells are inoculated into liquid medium. Sometimes, people who don't know about this unusual life style may end up being fooled." |
