Siderophores, defined as low-iron-induced virtually ferric-specific ligands, are widely distributed in microbial species where they function in the sequestration and transport of iron. In Escherichia coli biosynthesis of siderophores is negatively regulated at the transcriptional level by ferrous ion in conjunction with a repressor protein, Fur (ferric

Siderophore production by actinobacteria
BioMetals, 2014Produced by bacteria, fungi and plants, siderophores are low-molecular-weight chelating agents (200-2,000 Da) to facilitate uptake of iron (Fe). They play an important role in extracellular Fe solubilization from minerals to make it available to microorganisms.

There has been considerable effort expended in the investigation of the potential of siderophore conjugates of antibiotics to circumvent the permeability barrier imposed by the outer membrane of Gram‐negative bacteria. There is also a small group of natural conjugates, the sideromycins.

Bacterial siderophores promote plant growth: Screening of catechol and hydroxamate siderophores
International Journal of Phytoremediation, 2017The aim of the study was to determine the quality and quantity of siderophores produced by bacteria isolated from plants' roots. The second aim was to determine the effect of siderophores on plants growth (Festuca rubra L. and Brassica napus L.). The study was carried out using bacteria isolated from roots of: Arabidopsis thaliana L., F.

Siderophores are low molecular weight organic ligands exuded by some aerobic organisms and plants to acquire Fe under Fe-limited conditions. The hydroxamate siderophores may sorb to aluminosilicate clays through a variety of mechanisms depending upon the nature of the clay and of the siderophore along with solution conditions such as pH, ionic strength,

Chemistry and biology of siderophores
Natural Product Reports, 2010Siderophores are compounds produced by bacteria, fungi and graminaceous plants for scavenging iron from the environment. They are low-molecular-weight compounds (500-1500 daltons) possessing a high affinity for iron(III) (Kf > 1030), the biosynthesis of which is regulated by iron levels and the function of which is to supply iron to the cell.

Occurrence of Siderophores in Enterococci
Zentralblatt für Bakteriologie, 2000In 70 strains of the genus Enterococcus belonging to 16 species and isolated from clinical material, animals and the environment, a hydroxamic class of siderophores was detected with the aid of chemical and biological tests. A correlation between siderophore activity and species affiliation was found: E.

Efficient iron acquisition mechanisms are fundamental for microbial survival in the environment and for pathogen virulence within their hosts. M. robertsii produces two known iron-binding natural products: metachelins, which are used to scavenge extracellular iron, and ferricrocin, which is strictly intracellular.
