The Siderophore Metabolome of Azotobacter vinelandii [PDF]

Applied and Environmental Microbiology, 2016
ABSTRACT In this study, we performed a detailed characterization of the siderophore metabolome, or “chelome,” of the agriculturally important and widely studied model organism Azotobacter vinelandii . Using a new high-resolution liquid chromatography-mass spectrometry (LC-MS) approach, we found over 35 ...

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.

Phosphorus Nutrition and Growth of Cotton Plants Inoculated With Growth-Promoting Bacteria Under Low Phosphate Availability

Frontiers in Sustainable Food Systems, 2021
The low availability of phosphorus (P) in the soil drastically limits the world productivity of crops such as cotton. In order to contribute sustainably to the solution of this problem, the current study aimed to evaluate the capacity of phosphate ...

Efficacy Assessment of Montanide GEL 02 PR and Liposome‐Based Encapsulation as Adjuvants for an FrpA Subunit Vaccine Against Photobacteriosis in Solea senegalensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Photobacteriosis is a major threat to marine aquaculture, and the siderophore transporter FrpA represents a promising target for effective subunit vaccine development. In this study, we evaluated Montanide GEL 02 PR and phosphatidylcholine‐based liposomes as aqueous and safer alternatives to Freund's adjuvant for an FrpA‐based subunit vaccine ...

The Role of Iron and Siderophores in Infection, and the Development of Siderophore Antibiotics

Clinical Infectious Diseases, 2019
AbstractIron is an essential nutrient for bacterial growth, replication, and metabolism. Humans store iron bound to various proteins such as hemoglobin, haptoglobin, transferrin, ferritin, and lactoferrin, limiting the availability of free iron for pathogenic bacteria.

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

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.

Temperature, Disinfectant Concentration and Bacterial Innate Properties Influence the Disinfection of Bacterial Pathogens Relevant to Catfish Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Aquaculture systems suffer a wide range of losses, mostly due to bacterial disease outbreaks, and the use of disinfectants is a routine practice for controlling the spread of pathogenic organisms globally. Including Aeromonas hydrophila, Streptococcus agalactiae and Edwardsiella tarda, implicated for natural disease outbreaks and economic ...

Siderophores as tools and treatments

npj Antimicrobials and Resistance
AbstractIn the search for iron, an essential element in many biochemical processes, microorganisms biosynthesise dedicated chelators, known as siderophores, to sequester iron from their environment and actively transport the siderophore complex into the cell.
