Abstract

Abstract

The rapid expansion of rare earth elements （REEs） in high-tech and military fields and the shortage of exploitable resources are constantly widening the international supply gap. Since traditional REE enrichment processes （physical/chemical methods） are often associated with environmental pollution， microbial adsorption has been regarded as an important research focus for achieving the efficient utilization of REE resources and ensuring their sustainable development. Functional strains can effectively enrich REEs from low-concentration solutions through multi-level mechanisms， such as surface adsorption， biomineralization， and intracellular accumulation. At present， although this technology still faces challenges in practical applications， including insufficient environmental tolerance and high costs， the increasing number of related studies， such as strain modification， composite material development， and multi-process integration， is continuously promoting its large-scale application. In the future， continued exploration of functional strains， elucidation of their adsorption mechanisms， directional optimization of strain functionality， and further investigation of multi-process coupling technology， etc.， are expected to enable the industrial application of microbial technology for REE （ions） adsorption.
