Lanpepsy is a novel lanthanide-binding protein involved in the lanthanide response of the obligate methylotroph Methylobacillus flagellatus

Jethro L. Hemmann et al.

Summary: Lanthanides are required in certain methanol dehydrogenases, and the study of proteins involved in lanthanide sensing and utilization has become a popular field of research. This study focused on the lanthanome of Methyl-obacillus flagellatus and identified a novel lanthanide-binding protein called LanP. Bioinformatic analysis and experimental assays confirmed the presence of multiple lanthanide binding sites in LanP, highlighting its potential role in lanthanide utilization. This discovery has implications for the purification and separation of rare-earth elements.

Current nature-based biological practices for rare earth elements extraction and recovery: Bioleaching and biosorption

Rebecca M. Brown et al.

Summary: There is a growing worldwide demand for rare earth elements (REEs) that are essential for low-carbon energy transition, national security applications, and consumer electronics. This study focuses on nature-based biological methods (bio-leaching and biosorption) for REEs extraction from e-wastes and ore deposits. The narrative and systematic reviews reveal that biological methods are more environmentally friendly than conventional methods in the REE mining industry, and there has been rapid growth in bioleaching and biosorption research. The study concludes that targeted mixed REEs extraction can be a sustainable approach, and nature-based biological REE extraction solutions offer significant socio-economic and environmental benefits.

Rare earths stick to rare cyanobacteria: Future potential for bioremediation and recovery of rare earth elements

Michael Paper et al.

Summary: This study investigated the potential of 12 cyanobacterial strains for biosorption of rare earth elements, and Nostoc sp. 20.02 showed the highest adsorption capacity. Synechococcus elongatus UTEX 2973, Calothrix brevissima SAG 34.79, Desmonostoc muscorum 90.03, and Komarekiella sp. 89.12 were also promising strains. The adsorption of metals by the strains had fast kinetics and pH value had a significant impact on the process.

Hyperaccumulation of Gadolinium by Methylorubrum extorquens AM1 Reveals Impacts of Lanthanides on Cellular Processes Beyond Methylotrophy

Nathan M. Good et al.

Summary: Lanthanides (Ln), a new group of life metals, can be acquired and used by methylotrophic bacteria as cofactors with PQQ. A genetic variant of methylotrophic bacterium was found to efficiently accumulate heavy Ln and showed altered transcriptional response to heavy metal stress and methanol oxidation. The study also provided new insights into stress homeostasis and strategies for Ln recovery.

Separation and Recycling Potential of Rare Earth Elements from Energy Systems: Feed and Economic Viability Review

Ajay B. Patil et al.

Summary: This review explores the potential and importance of recycling rare earth elements (REEs) from different energy conversion systems. REEs are abundant in nature but expensive and challenging to extract and separate. The overall demand for REEs is growing, and recycling is crucial to supplement conventional mining. However, the current REE recycling situation is weak, with only a small percentage being recovered. The profitability of REE recycling depends on processing costs and element prices, emphasizing the importance of focusing on valuable and critical REEs in end-of-life products.

A comparative state-of-technology review and future directions for rare earth element separation

Emmanuel Ohene Opare et al.

Summary: This study provides an overview of existing REE production and recovery pathways, highlighting the top three most explored separation techniques (leaching, solvent extraction, and plasma) and study fields (chemistry, engineering, and metallurgy). The dominant REE separation technique across various research fields was found to be the use of acids, bases, ionic liquids, and salts for leaching REEs. The study also suggests the agromining approach as a practical method for sustainable REEs recovery from secondary sources and end-of-life products.
