| Abstract Scope |
Over the past few decades, various biomaterial-based separations of rare earth elements (REEs) have been studied, due to their high selectivity and potential for environmentally friendly separation systems. However, challenges remain in addressing the energy and material production costs for these routes. To tackle this issue, we present an innovative approach utilizing viruses as novel tools for the bioseparation of REEs. Specifically, we engineer the major coat protein of the Fd phage to express two peptides: lanthanide-binding peptide (LBP) and elastin-like peptide (ELP). The LBP facilitates selective binding of lanthanides in a pH-dependent manner, while the ELP enables temperature-dependent precipitation in an aqueous solution. By modulating pH and temperature, the phage can selectively separate REEs from a mixture. This phage-based method shows significant potential for advancing sustainable REE separation, offering an energy- and cost-effective solution. |
