Photosystem modulation and extracellular silicification in green microalgae: Key strategies for lead tolerance and removal.

ABSTRACT: The escalating contamination caused by lead ions (Pb²⁺) and its harmful effects on all life forms has raised global concerns. Certain microalgae thrive in metal mining sites characterized by low pH and high concentrations of Pb²⁺, which are usually prohibitive for many microorganisms. Little is known about the mechanisms underlying the adaptation of such microalgae to these hostile conditions. In this study, we elucidated the adaptive strategies of the green microalga Micractinium belenophorum strain AUMW, isolated from a lead mining site, and its application for the removal of Pb⁺². Results revealed that strain AUMW can efficiently tolerate up to 200 ppm of Pb⁺² in an F/2 medium. Further experimental variables were optimized through respo
