Abstract

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.
