Genes Involved in the Biosynthesis and Transport of Acinetobactin in [PDF]

Genomics & Informatics, 2015
Pathogenic bacteria survive in iron-limited host environments by using several iron acquisition mechanisms. Acinetobacter baumannii, causing serious infections in compromised patients, produces an iron-chelating molecule, called acinetobactin, which is ...

Virulence Factors in Colorectal Cancer Metagenomes and Association of Microbial Siderophores with Advanced Stages

Microorganisms, 2022
Colorectal cancer (CRC) is a growing public health challenge, featuring a multifactorial etiology and complex host–environment interactions. Recently, increasing evidence has pointed to the role of the gut microbiota in CRC development and progression ...

Functional Plasticity of Microbial Siderophores in Iron- and Boron-Rich Niches

Applied Microbiology
Siderophores are high-affinity iron-chelating metabolites that underpin microbial survival in iron-limited environments and play central roles in metal homeostasis, ecological competition, and pathogenesis.

Distribution and Cycling of Siderophores in the Eastern North and Tropical Pacific Oceans

Geophysical Research Letters
Most iron (Fe) dissolved in seawater is complexed to organic ligands of unknown composition. Here we investigate the distribution of siderophores, small organic compounds synthesized by microbes to bind environmental Fe and facilitate its transport into ...

Siderophore production in Botryosphaeriaceae fungi associated with grapevine trunk diseases

The Microbe
Fungi from the Botryosphaeriaceae are recognized as causal agents of dieback diseases in a variety of economically important woody plants, including grapevine. Some species produce secondary metabolites that may function as virulent factors.

Chemistry and biology of siderophores

, 2010
Siderophores 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) (K-f > 10(30)), the ...

Siderophores in forest soil solution

, 2004
Siderophores in soil solution of coniferous forest soils have been chemically identified for the first time. We have identified the siderophores ferrichrome and ferricrocin in soil solution of the upper organic layer by High Performance Liquid ...

Production of siderophore type chelates by mixed bacterioplankton populations in nutrient enriched seawater incubations [PDF]

, 2004
Siderophore type chelates were isolated from nutrient enriched seawater collected from coastal and near shore environments and detected using a novel high performance liquid chromatography – electrospray ionisation – mass spectrometric technique ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

Biotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Hydroxamate siderophores: occurrence and importance in the Atlantic Ocean

, 2008
Siderophores are chelates produced by bacteria as part of a highly specific iron uptake mechanism. They are thought to be important in the bacterial acquisition of iron in seawater and to influence iron biogeochemistry in the ocean.
