Bacterial iron acquisition by Escherichia coli is facilitated by amino acid complexation in a rapid-renewal environment | PNAS In natural environments, bacteria often encounter low concentrations of nutrient mixtures that are continuously replenished by physical processes s...

🔥Hot off the press!

❓ How do bacteria get iron when nutrients are scarce and constantly washed away❓

A PriME collective effort reveals—using a new continuous culture device—how bacteria acquire iron under rapid nutrient renewal, beyond #siderophores.

Bioinorganic #ChemSky practical course @hhu.bsky.social finished! The remains of our experiments with #siderophores look like Christmas tree ornaments! The blue color arises from the CAS dye with Iron. On some agar plates Bacteria grow that produce ligands to steal iron, inducing the color change 🥽

Deep-Sea Discovery Shines Light on Life in the Ocean’s Mysterious Twilight Zone The ocean's twilight zone is iron-deficient, limiting bacterial growth and affecting carbon storage. New findings show high siderophore levels in deeper waters, indicating a broader impact on marine b...

“Unlike in surface waters, we did not expect to find siderophores in the ocean’s twilight zone,” said Conway. “Our study shows that iron-deficiency is high for bacteria living in this region...use #siderophores to increase their uptake of iron."
