A Trend‐Based Two‐Stage Framework for Tin (Sn) Recovery From Waste PCBs via Bioleaching and Thermally Activated Bentonite Adsorption

Journal of Chemistry, Volume 2026, Issue 1, 2026.
This study proposes a two‐stage, trend‐based framework for tin (Sn) recovery from waste printed circuit boards (PCBs) by integrating Acidithiobacillus ferrooxidans–mediated bioleaching with thermally activated bentonite adsorption. Bioleaching performance was optimized using a central composite design–based response surface methodology (CCD‐RSM), which

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...
