Biosynthesis Pathways, Transport Mechanisms and Biotechnological Applications of Fungal Siderophores
Journal of Fungi, 2021 Iron (Fe) is the fourth most abundant element on earth and represents an essential nutrient for life. As a fundamental mineral element for cell growth and development, iron is available for uptake as ferric ions, which are usually oxidized into complex ...

Cyanobacterial Siderophores—Physiology, Structure, Biosynthesis, and Applications
Marine Drugs, 2019 Siderophores are low-molecular-weight metal chelators that function in microbial iron uptake. As iron limits primary productivity in many environments, siderophores are of great ecological importance.

Siderophores: More than Stealing Iron
mBio, 2016 Siderophores are small molecular iron chelators that are produced by microbes and whose most notable function is to sequester iron from the host and provide this essential metal nutrient to microbes.

Antibiotic resistance and siderophores production by clinical Escherichia coli strains
BioTechnologia, 2022 The phenomenon of antibiotic resistance has dramatically increased in the last few decades, especially in enterobacterial pathogens. Different strains of Escherichia coli have been reported to produce a variety of structurally different siderophores.

EFFECT OF SIDEROPHORES AGAINST E. COLI O157:H7
Italian Journal of Food Safety, 2012 In this study, the inhibiting activity of siderophores produced by Pseudomonas fluorescens against Escherichia coli O157:7 was assayed. Siderophores were extracted from P. fluorescens cultures and preliminarily tested by C.A.S. reagent and UV.
