The nutritional conditions controlling iridescence inPseudomonas aeruginosa were studied using synthetic media solidified with agar. Iron and magnesium were growth-limiting factors in media solidified with dialysed agar. Iridescence only occurred on iron-deficient media and was not suppressed by adding Ca, Cu, Mn and Zn to these media. The ultraviolet absorption spectrum of the iridescent material was almost identical to the spectrum of the pyo I substances which are 2-alkyl-4-quinolinols. The… CONTINUE READING
