Rational Design of a Synthetic Galliphore for the Diagnostic Nuclear Imaging and Treatment of Bacterial Infections

Angewandte Chemie, EarlyView.
KO‐NH2 is a synthetic metallophore that preferentially binds Ga3+ over Fe3+ and is recognized by bacterial transporters. Photocrosslinking identifies CirA and Fiu as key uptake proteins in E. coli. KO‐NH2 enables targeted imaging and treatment of E. coli soft tissue infections.

Polychip‐A High‐Throughput Droplet Microfluidics Platform for Interrogating Microbial Interactions

Advanced Science, EarlyView.
Polychip, a fully integrated droplet microfluidics platform, enables high‐throughput, single‐cell resolution screening of polymicrobial interactions. By seamlessly combining six automated microfluidics operations on a single chip, the system accelerates antimicrobial discovery by 11 to 14 times compared to traditional robotic methods.

Pseudomonas siderophores: production, spectrophotometry detection and Botrytis suppression

Notulae Scientia Biologicae
Siderophores are iron-chelating agents produced by almost all microorganisms in response to iron deficiency. Due to the requirement of iron for cell growth and metabolism, siderophore-mediated acquisition of iron plays a central role in determining the ...

Disrupting Helicobacter pylori Iron Homeostasis With Bismuth Nanodrug‐Mediated Nutritional Trap for Targeted Gastric Infection Therapy

Advanced Science, EarlyView.
A “nutritional trap” strategy centered on disrupting bacterial iron homeostasis is proposed. The synthesized Bi‐TP@FU (TBF) can target Helicobacter pylori, interfere with the bacterial iron uptake and utilization processes to disrupt its iron homeostasis, induce bacterial death, and meanwhile preserve the balance of the intestinal flora.

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

Advanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.

Mechanistic insights into a novel exporter-importer system of Mycobacterium tuberculosis unravel its role in trafficking of iron. [PDF]

PLoS ONE, 2008
Elucidation of the basic mechanistic and biochemical principles underlying siderophore mediated iron uptake in mycobacteria is crucial for targeting this principal survival strategy vis-à-vis virulence determinants of the pathogen.

Differences in Siderophore Production During the Growth of Phytoplankton in Southern Ocean Incubation Experiments Under High- and Low-Iron Conditions. [PDF]

Environ Microbiol
Experiments performed in the Southern Ocean under low‐ and high‐iron conditions showed that the heterotrophic bacteria community produced distinct iron‐binding compounds called siderophores, depending on the environmental conditions, despite similar bacteria communities being present in each experiment.
