Iron is an essential trace element for most organisms. A common way for bacteria to acquire
this nutrient is through the secretion of siderophores, which are secondary metabolites that …

The ability to form biofilms is a crucial virulence trait for several microorganisms, including
Klebsiella pneumoniae–a Gram-negative encapsulated bacterium often associated with …

To maintain iron homeostasis within the cell, bacteria have evolved various types of iron
acquisition systems. Ferric iron (Fe3+) is the dominant species in an oxygenated …

Simple Summary The human pathogen Pseudomonas aeruginosa (P. aeruginosa) causes
several infections, both acute and chronic, mainly in hosts with compromised immunity and …

In the ancient anaerobic environment, ferrous iron (Fe2+) was one of the first metal
cofactors. Oxygenation of the ancient world challenged bacteria to acquire the insoluble …

Iron is an indispensable metabolic cofactor in both pro-and eukaryotes, which engenders a
natural competition for the metal between bacterial pathogens and their human or animal …

Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

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 …

Iron is one of the major limiting factors and essential nutrients of microbial life. Since in
nature it is not readily available in the preferred form, microorganisms produce small high …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …
