Droop (1951) Isolator Number: Deposition: CCAP (3/55) Relatives: ?UTEX 2089; CCAP 1052/6 aka SMBA 14 [?Millport 14]; SAG 1090-6; NIBB 3009 aka ORI-B15N, NIBB 3010 Also Known As: Nitzschia closterium f. minutissima aka T-form Notes: 1974 renamed by J.C. Lewin (pers. Comm.); light harvesting pigment proteins, monospecific antibodies (Friedman & Alberte 1987); guanine metabolism (Allison & Syrett 1987); urea metabolism/nickel & nitrogen deprivation effect (Syrett & Peplinska 1988); antifungal activity (Kellam et al. 1989); lipid content (Yongmanitchae & Ward 1991); (Lewin 1958); 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."
