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 …

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 …

Iron nutrition in microbes and higher organisms has become a most fascinating topic in
microbiology and biotechnology. Extensive studies in a variety of microorganisms have …

Most bacteria, fungi, and some plants respond to Fe stress by the induction of high-affinity Fe
transport systems that utilize biosynthetic chelates called siderophores. To competitively …

Although a stimulating review by JB Neilands in 1957 [1] correctly identified the
physiological function of certain microbial ferric chelators, it was in 1973 that Charles …

Streptomyces pilosus is one of several microbes which produce ferrioxamine siderophores.
In the accompanying paper (G. Müller and K. Raymond, J. Bacteriol. 160: 304-312), the …

The possession of specialized iron transport systems may be crucial for bacteria to override
the iron limitation imposed by the host or the environment. One of the most commonly found …

The insolubility of Fe 3+ necessitates special mechanisms for iron acquisition in most
organisms. Bacteria use siderophores to chelate Fe 3+ and iron in heme, hemoglobin …
