Bacterial siderophores in community and host interactions

, 2020
Iron is an essential trace element for most organisms. A common way for bacteria to acquire this nutrient is through the secretion of siderophores, which are secondary metabolites that scavenge iron from environmental stocks and deliver it to cells via ...

Genome Mining for Microbial Siderophores: Improving Structural Predictions [PDF]

, 2020
Nearly all life requires iron; however, under aerobic conditions, Fe(III) is nearly insoluble. To meet their metabolic needs, many bacteria synthesize siderophores: small-molecule, high-affinity Fe(III) chelators.

Production, characterization and iron binding affinity of hydroxamate siderophores from rhizosphere associated fluorescent Pseudomonas

Journal of Plant Protection Research, 2018
Fluorescent Pseudomonas (FP) is a major group of plant growth promoting rhizobacteria and a well-known synthesizer of siderophores, which imparts a selective advantage on rhizosphere competence and their biocontrol traits.

Impact of the GouM transporter on secondary metabolism activation and production yield in Streptomyces noursei strain CK‐15

New Plant Protection, EarlyView.
Overexpression of the gouM transporter gene in Streptomyces noursei CK‐15 enhances gougerotin production by 114% and activates silent biosynthetic gene clusters. This finding links transporter activity to metabolite efflux and secondary metabolism, offering a strategy for natural product discovery and strain optimization.

Combined application of Bacillus velezensis JDB15 and Trichoderma harzianum JDL4 suppresses banana Fusarium wilt under controlled conditions

Pest Management Science, EarlyView.
The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.

Biocontrol and plant growth‐promoting potential of Streptomyces strains against fungal pathogens of tomato and wheat for a sustainable agriculture

Pest Management Science, EarlyView.
This study highlights the biocontrol potential of Streptomyces strain Strep_22. In vitro, it inhibits key fungal pathogens by 91.52%. In vivo, it significantly reduces disease incidence in wheat and tomato while enhancing biomass, shoot, and root development, offering a highly promising, sustainable ecological alternative to chemical pesticides ...

Quantitative Imaging of Human Hemoglobin Binding to Staphylococcus aureus With Single‐Molecule Resolution

Small, EarlyView.
Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.

Structural Prediction and Unique Reactivity of Novel Siderophores [PDF]

, 2021
Iron is an essential nutrient for virtually all life on earth. Bacteria often live in highly iron-limiting conditions such as the ocean, where iron levels are naturally low and where bioavailable iron is hindered by the favorable formation of insoluble ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.
