Iron is essential to virtually all organisms, but poses problems of toxicity and poor solubility.
Bacteria have evolved various mechanisms to counter the problems imposed by their iron …

Because of their ability to transform atmospheric N2 into ammonia that can be used by the
plant, researchers were originally very optimistic about the potential of associative …

Organisms generally respond to iron deficiency by increasing their capacity to take up iron
and by consuming intracellular iron stores. Escherichia coli, in which iron metabolism is …

Almost all organisms require iron for enzymes involved in essential cellular reactions.
Aerobic microbes living at neutral or alkaline pH encounter poor iron availability due to the …

Kin selection theory predicts that the damage to a host resulting from parasite infection
(parasite virulence) will be negatively correlated to the relatedness between parasites within …

Virulence factors of Escherichia coli are of two main types; those produced on the surface of
the cell and those produced within the cell and then exported to the site of action. Those on …

The filamentous ascomycete A. nidulans produces two major siderophores: it excretes
triacetylfusarinine C to capture iron and contains ferricrocin intracellularly. In this study we …

As stated in an Chapter 4, prokaryotes of both Domains or Superkingdoms, the Bacteria and
the Archaea, mediate the formation of a large number of diverse minerals. They are known …

Escherichia coli possesses a TonB-dependent transport system, which exploits the iron-
binding capacity of citrate and its natural abundance. Here, we describe three structures of …
