Quantification of hydroxamate siderophores
in soil solutions of podzolic soil profiles in Sweden.
maltaromaticum involved in accessing iron in myoglobin was examined by evaluating the production of siderophores
using a chrome azurol S (CAS) assay, and by examining the ability to bind heme, an iron compound, by growing the culture in a medium containing hematin.
The salicylate-derived mycobactin siderophores
of Mycobacterium tuberculosis are essential for growth in macrophages.
Protection of cucumber against Pythium root rot by fluorescent pseudomonads: predominant role of induced resistance over siderophores
2006) used a compost tea produced from grape marc waste to inhibit the growth of several soil-borne phytopathogenic fungi; it was concluded that the production of siderophores
by the microbial species within the compost tea was responsible for reducing the effects of the fungal pathogen.
Among the topics are siderophores
from bacteria and from fungi, haem uptake and iron extraction by bacteria, mechanisms and regulation of iron homeostasis in the Rhizobia, iron uptake in Shigella and Escherichia coli, haem and iron metabolism in Bacteriodes, iron dependence and transport in Cyanobacteria, and iron uptake in Staphylococci.
Much of the iron in ocean water is strongly bound to natural organic chelators, such as siderophores
, which bind and release iron in different ways.
In order to survive in a human host, bacteria form siderophores
called iron-regulated outer membrane proteins (IROMPs).
The researchers examined bacterial communities enveloping particles of sand and identified chemicals - called siderophores
- produced by cultivable bacteria that act as growth factors for distantly related strains of uncultivable bacteria.
are low- molecular weight multidentate ligands.
Bacteria and fungi counter these defenses by producing siderophores
, which are proteins that are synthesized and exported to capture iron, with the resulting iron-siderophore
complex endocytosed for use (3).
This is the same geometry and distances found in many known siderophores
