“…Understanding of microbially-mediated REE-bearing phosphate mineral weathering may inform the development of new biomining strategies for extraction of REEs from low grade mine tailings (Zhuang et al , 2015; Corbett et al , 2018; Corbett and Watkin, 2018). As sequestration of phosphate into secondary REE phases can limit P bioavailability in agricultural soils, the current study motivates investigation of microbial processes that can dissolve REE/P-bearing minerals.…”

“…The combination of native consortia presents on the ore with the inoculation of a PSM leached a greater amount of RE than a single PSM or than the native population alone, due to a syntrophic effect between populations (Corbett et al, 2018). In addition, PSM produce both alkaline and acid phosphatases, either intracellular or secreted extracellularly, enable the hydrolysis of phosphoric compounds and the release of RE into the leachate.…”

“…In addition, PSM produce both alkaline and acid phosphatases, either intracellular or secreted extracellularly, enable the hydrolysis of phosphoric compounds and the release of RE into the leachate. The combination action of acid phosphatase activity and organic acids increase RE solubilization in monozite (Corbett et al, 2018). More information for microbial RE mobilization from solid matrices were reviewed by Brandl et al (2016).…”

Rare earth (RE) elements are a group of 17 chemical elements including the 15 lanthanides plus Yttrium and Scandium. RE have been identified as critical elements due to their special properties (e.g., catalytic, metallurgical, nuclear, electrical, magnetic, and luminescent) and various applications in many modern technologies, environment and economic areas. Thus, the demand for RE has increased significantly during the last decades. This demand has induced an increase in mining activities and consequently a release of RE into the surrounding environment, causing a potential threat to human health and the environment. Therefore, investigations leading to new solutions for the RE recycling from alternate resources like electronic, mining and industrial wastes, has been rapidly growing. In spite of that, recycling stays extremely difficult, expensive and is currently not seen as a significant solution. The concept of phytomanagement is a promising solution when conventional mining methods are no longer cost-effective, not to mention all the ecosystem services provided by plants. The phytoextraction service allows the extraction and recovery of RE from soils or industrial wastes (e.g., phosphogypsum from phosphoric acid production) with the prospect of economic added value. To date, some twenty hyperaccumulator plant species (almost ferns such as Dicranopteris dicthotoma) accumulate high concentrations of RE especially in their erial parts. While the potential roles of native bacteria in mobilization of RE from ores remains slightly documented, those of Plant Growth Promoting Rhizobacteria (PGPR) is much less. PGPR are indeed able to mobilize metals and/or to stimulate plant development in the aim to increase the amount of RE extracted by the plant with then a higher phytoextraction efficiency. Yet to date, only a few studies have been devoted to RE using coupled bioaugmentation-phytoextraction. This review summarizes the data regarding 1) the source of RE (RE-accumulating sediments, soils naturally rich in RE, wastes) and their bioavailability in these matrices, 2) plants identified as RE hyperaccumulator and their potential for RE phytomining, 3) isolation and selection of indigenous bacteria stemming from RE contaminated matrices, such as soil, for their potential ability to increase phytoextraction performances and 4) bioaugmentation-assisted phytoextraction studies dealing with RE.

“…However, bioleaching offers some Previous works have determined remarkable alterations in the natural microbial populations during bioleaching of monazite ores. The existence of native Firmicutes on the monazite seems to have significantly contributed to the increase in REE leaching observed when using non-sterilized monazite [38].…”

Rare earth elements (REE) are essential in high-technology and environmental applications, where their importance and demand have grown enormously over the past decades. Many lanthanide and actinide minerals in nature are phosphates. Minerals like monazite occur in small concentrations in common rocks that resist weathering. Turquoise is a hydrous phosphate of copper and aluminum scarcely studied as copper ore. Phosphate-solubilizing microorganisms are able to transform insoluble phosphate into a more soluble form which directly and/or indirectly contributes to their metabolism. In this study, bioleaching of heavy metals from phosphate minerals by using the fungus Aspergillus niger was investigated. Bioleaching experiments were examined in batch cultures with different mineral phosphates: aluminum phosphate (commercial), turquoise, and monazite (natural minerals). The experiments were performed at 1% pulp density and the phosphorous leaching yield was aluminum phosphate > turquoise > monazite. Bioleaching experiments with turquoise showed that A. niger was able to reach 8.81 mg/l of copper in the aqueous phase. Furthermore, the fungus dissolved the aluminum cerium phosphate hydroxide in monazite, reaching up to 1.37 mg/L of REE when the fungus was grown with the mineral as the sole phosphorous source. Furthermore, A. niger is involved in the formation of secondary minerals, such as copper and REE oxalates.
