“…The sorption capacity of Pr(III) on P. aeruginosa reached 0.94 mmol Pr g −1 . However, for Spirulina the maximum biosorption uptake of Ce(III) according to the Langmuir model was 18.1–38.2 mg/g, which is much higher than the sorption capacities found in our study.…”

“…For Ce(III; cerium, z = 58) ions biosorption from aqueous solutions by cyanobacteria ( Spirulina sp.) increased on increasing the pH, showing the optimum pH range between 5.0 and 5.5 . The optimum pH value for biosorption of Nd(III; neodymium, z = 60) ions at 30°C was pH 5.0 while at 50°C, the maximum experimental uptake was obtained at pH 4.0 for the microalgae Chlorella vulgaris .…”

The ascomycetous fungus, Botryosphaeria rhodina MAMB-05, secretes a (1!3)(1!6)β-D-glucan, and the scaled-up production of this β-glucan results in large amounts of mycelial biomass being produced that represent a potentially cost-effective biosorbent for rare-earth elements. High sorption capacities for both La(III) and Sm(III) were demonstrated for viable and autoclaved lyophilized fungal mycelium. Fourier-transformed infra-red absorption spectra and the point of zero charge (PZC) were similar for the viable and inactive fungal mycelia. The rare-earth lanthanide elements (La and Sm) binding increased at initial pH values greater than 5.0, which was also observed for the PZC determination. The maximum La(III) uptake capacity was observed at lower amounts of La(III) ions in solution, decreasing from 100.0 to 25.3% when the initial lanthanide concentration increased from 15 to 100 mg/L. Lanthanide biosorption by B. rhodina MAMB-05 mycelia followed the Langmuir model, and the affinity of biosorbent functional groups was similar for La(III) and Sm(III).

“…Interestingly, some REEs, namely Ce, Gd, La, and Sc, have been reported to increase the growth of some microalgae and their content of lutein, violaxanthin, β-carotene, and chlorophylls (Goecke et al 2017). Microalgae from the Arthrospira and Chlorella genera were also experimentally shown to bioconcentrate some REEs such as Ce or Nd (Sadovsky et al 2016;Kücüker et al 2017). In the present study, all studied microalgal food supplements, except for one product based on Spirulina (exceeding maximum allowance limit) and one based on Chlorella (reaching 78% of the limit), were characterized by a relatively low content of REEs.…”

Arthrospira spp. (known commercially as Spirulina) and Chlorella spp., valued for their evidence-based nutritional and bioactive properties, are cultivated for the purpose of production of food supplements for worldwide distribution. However, the quality and safety of the final product depends on culturing and manufacturing conditions. The present study investigated the content of toxic elements (As species, Al, Cd, Hg, Ni, Pt, Pb, Cr (VI), rare earth elements) and minerals (Ca, Co, Cr, Cu, Fe, K, Na, Mg, Mn, P, Zn) in Chlorella (n = 10) and Spirulina (n = 13) food supplements registered in the European Union. Considering the most common recommended daily dosage 3.0, supplementation with any of the studied product would contribute significantly to mineral intake, with the exception of Fe which was found at high but acceptable levels in both Spirulina and Chlorella formulas. The majority of products revealed agreement between factual mineral content and that declared on the label, the only exception being Cu content in Chlorella products found to be significantly higher (> 130%). All studied supplements were found to have Cd, Hg, and Ni levels much below safety limits, although selected ones were characterized by increased content of Al, Pb, and inorganic As. No hexavalent Cr was detected in the studied products. The study highlights that microalgal supplements can be safe for consumers if appropriate measures are taken to ensure consumer safety, although it underlines the continuous need to monitor these products in order to fully eliminate those of low quality.

“…The separation of lanthanides utilizing different methods, including solvent extraction (Wang et al, 2017); plasma separation (Gueroult et al, 2018); hydrothermal (Josso et al, 2018), alkaline, and acid extraction (King et al, 2018); adsorption (Awual et al, 2013); and biosorption (Das & Das, 2013;Fomina & Gadd, 2014;Sadovsky et al, 2016;Elsalamouny et al, 2017) has been reported. In principle, precipitation and solvent extraction methods have technical limitations for treating a contaminated aqueous solution; for example, they require some pre-treatments involving physical and chemical processes.…”

Lanthanides in aqueous waste streams have received great attention due to their ability to pollute the environment. Therefore, efforts have been devoted to adsorbing lanthanides from waste industries. The evaluation of agro-waste by determining the adsorption efficiency of Ln 3+ ions is an important step in developing a process for Ln 3+ removal from water systems, as well as a method of isolating Ln 3+ ions from mineral ores, such as low-grade bauxite. The adsorption performance of banana peels (Musa paradisiaca L.) was evaluated in the removal of Ln 3+ ions. In addition, the adsorption of lanthanide ions from an aqueous solution in a multicomponent system was studied using activated carbon from banana peels. The selection of the best adsorbent was done by the iodine number method, where activated carbon had the highest iodine absorbance at 572.2 mg/g. The use of activated carbon as an adsorbent for the removal of commercial lanthanide ions from an aqueous solution was evaluated. The optimum condition in the Ln 3+ multicomponent system for the adsorption of Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ ions was determined to be a contact time of 2.5 h, a pH of 4, and an adsorbent dosage of 100 mg. The present research further supports the possibility of the adsorption of Ln 3+ ions from low-grade bauxite with adsorption efficiencies of 67.6, 71.0, 65.0, 62.9, and 56.6% for Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ , respectively.
