Effect of Iron Limitation on "Pseudomonas plantarii" Growth and Tropolone and Protein Production.
The addition of iron to an iron-deficient medium markedly enhanced the growth of "Pseudomonas plantarii" and the production of red crystals. However, it markedly reduced the amount of dissolved tropolone, a product of the bacterium and an iron chelator, and the production of an iron-regulated protein (78 kilodaltons). The red crystal was complex, composed of tropolone and iron, the ratio being 3:1.
