Sensitivity of Iron-Oxidizing Bacteria, Thiobacillus ferrooxidans and Leptospirillum ferrooxidans , to Bisulfite Ion [PDF]

Applied and Environmental Microbiology, 1994
When grown on iron-salt medium supplemented with the bisulfite ion, Leptospirillum ferrooxidans was much more sensitive to the ion than was Thiobacillus ferrooxidans . The causes of the sensitivity of L. ferrooxidans to the bisulfite ion were studied. The bisulfite ion

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, Volume 12, Issue 29, August 7, 2025.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Lanmodulin‐Decorated Microbes for Efficient Lanthanide Recovery

Advanced Materials, Volume 37, Issue 10, March 12, 2025.
Bio‐scaffolded lanmodulin (LanM) on E. coli is developed as a simple, effective material for repeated capture and release of rare earth elements (REEs). Over 80% of four REE cations are captured, even in the presence of excess competitive ions. The material can be employed in a filtration flow‐through system with a capture capacity of 11.8 ± 0.9 mg g−1
