Influence of temperature on the iron metabolism of a fluorescent pseudomonad.

The iron requirement for maximal cell yields of a fluorescent pseudomonad increases as the temperature of incubation is increased. On a succinate salts medium, maximal cell yields are attained at iron concentrations of 0.10 mug/ml of added iron at 20 C and at 3.0 mug/ml of added iron at 28 C. This bacterium does not grow in the basal medium at 31 C even in the presence of 0.01 to 10 mug/ml of added iron. The inability to grow at the higher temperature is due to the loss, by this organism, of its ability to biosynthesize hydroxamate iron transport compounds at temperatures of 28 C and above, since supplementation with such compounds produced by this organism at lower temperatures promoted growth at 31 C. The biosynthesis of these compounds at lower temperatures contributes to the efficient utilization of iron by the bacterium.

Role of microbial iron transport compounds in bacterial spoilage of eggs.

Microbial iron transport compounds, belonging either to the hydroxamate family excreted by pseudomonads, or to the phenolate family excreted by salmonellae, reverse the bacteriostatic effect of conalbumin on the growth of these bacteria in egg white. The presence of microgram quantities of these compounds permits both salmonellae and pseudomonads to reach dense populations in egg white. The role of these iron transport compounds in bacterial egg spoilage is discussed.

Enterobactin, an iron transport compound from [formula omitted

Enterobactin, a physiologically active iron sequestering agent, is excreted into the medium by Salmonella typhimurium under low iron conditions. It is a cyclic polyester consisting of three residues of 2,3-dihydroxy-N-benzoylserine.
