This chapter concentrates on siderophores produced by fungi. It covers the uptake
processes of ferrisiderophores in fungi that have been studied. Natural hydroxamate …

A variety of fungi are able to synthesize iron chelating compounds (siderophores) which are
excreted into the cultivation medium for iron sequestering purposes. Most ascomycetous …

Siderophores are low molecular weight, iron-chelating ligands produced by nearly all
microorganisms. Fungi synthesize a wide range of hydroxamate siderophores. This review …

Microbial iron chelates, called siderophores, are synthesized by bacteria and fungi in
response to low iron availability in the environment. The present review summarizes …

Siderophores (from the Greek:“iron carriers”) are defined as relatively low molecular weight,
ferric ion specific chelating agents elaborated by bacteria and fungi growing under low iron …

Siderophores are a group of natural compounds, produced by aerobic microorganisms to
acquire and transport ferric iron under iron-stress conditions. The iron (III) chelating groups …

In Gram-negative bacteria an iron-deficient state is required for both induction of desferri-
siderophores and overproduction of the cognate outer membrane receptor proteins. Thus …

A variety of fungi are known to overproduce and excrete desferri-siderophores under iron
limitation. After complexing with ferric iron, octahedral complexes are formed and taken up …

Iron is of great importance for many metabolic processes since the redox potential between
its two valence states Fe 2+ and Fe 3+ lies within the range of physiological processes …

Ecology of siderophores, as described in the present review, analyzes the factors that allow
the production and function of siderophores under various environmental conditions …
