Abstract :
[en] Heavy metal contamination poses a significant environmental threat due to its persistence, toxicity, and accumulation in ecosystems. Microbial bioremediation is increasingly recognized as a sustainable alternative to conventional treatment methods. This review discusses the main microbial mechanisms involved in metal detoxification, including biosorption, bioaccumulation, biomineralization, and resistance pathways. Current limitations and future research perspectives aimed at improving process efficiency and scalability are also highlighted. [fr] La contamination par les métaux lourds constitue une menace environnementale importante en raison de leur persistance, de leur toxicité et de leur accumulation dans les écosystèmes. La bioremédiation microbienne est de plus en plus reconnue comme une alternative durable aux méthodes de traitement conventionnelles. Cette revue examine les principaux mécanismes microbiens impliqués dans la détoxification des métaux, notamment la biosorption, la bioaccumulation, la biomineralisation et les voies de résistance. Les limites actuelles ainsi que les perspectives de recherche visant à améliorer l’efficacité et l’applicabilité à grande échelle des procédés sont également mises en évidence.
