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)

Cyanophage Infections in a Sponge Intracellular Cyanobacterial Symbiont
Environmental Microbiology, Volume 27, Issue 7, July 2025.Intracellular cyanobacterial symbionts of sponges are shown to be susceptible to cyanophages, challenging assumptions about their isolation from viral exposure. The study reveals novel phage–host interactions and suggests conserved infection strategies across symbionts of marine and terrestrial animals.

Bioleaching of anilite by Acidithiobacillus ferrooxidans
Transactions of Nonferrous Metals Society of China, 2008 Abstract In order to characterize the efficiency of copper bioleaching from anilite using pure cultures of Acidithiobacillus ferrooxidans in the absence and presence of ferrous sulphate, the experiments were carried out in shake flasks with or without 4 g/L ferrous sulphate (FeSO 4 ·7H 2 O) at pH 2.0, 150 r/min and 35°C.

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,
