“…This is in good agreement with the data published for brown algae by Vijayaraghavan et al (2010Vijayaraghavan et al ( , 2011 and Bulgariu and Bulgariu (2012). Kazak et al (2018) tested REE sorption u s i n g s e v e r a l s t r a i n s o f h e t e r o t r o p h i c b a c t e r i a (Microbacterium sp., Curtobacterium sp., Bacillus subtilis, Pseudomonas putida, and Bacillus pumilis) at pH 2 and 4 and reported in each case higher sorption coefficients at higher pH. Comparably, Tunali and Yenigun (2021) found higher sorption capacities for Nd and C. vulgaris at pH 5 in comparison to pH 4 and 6.…”

Whilst the biosorption of metal ions by phototrophic (micro)organisms has been demonstrated in earlier and more recent research, the isolation of rare earth elements (REEs) from highly dilute aqueous solutions with this type of biomass remains largely unexplored. Therefore, the selective binding abilities of two microalgae (Calothrix brevissima, Chlorella kessleri) and one moss (Physcomitrella patens) were examined using Neodym and Europium as examples. The biomass of P. patens showed the highest sorption capacities for both REEs (Nd3+: 0.74 ± 0.05 mmol*g−1; Eu3+: 0.48 ± 0.05 mmol*g−1). A comparison with the sorption of precious metals (Au3+, Pt4+) and typical metal ions contained in wastewaters (Pb2+, Fe2+, Cu2+, Ni2+), which might compete for binding sites, revealed that the sorption capacities for Au3+ (1.59 ± 0.07 mmol*g−1) and Pb2+ (0.83 ± 0.02 mmol*g−1) are even higher. Although different patterns of maximum sorption capacities for the tested metal ions were observed for the microalgae, they too showed the highest affinities for Au3+, Pb2+, and Nd3+. Nd-sorption experiments in the pH range from 1 to 6 and the recorded adsorption isotherms for this element showed that the biomass of P. patens has favourable properties as biosorbent compared to the microalgae investigated here. Whilst the cultivation mode did not influence the sorption capacities for the target elements of the two algal species, it had a great impact on the properties of the moss. Thus, further studies are necessary to develop effective biosorption processes for the recovery of REEs from alternative and so far unexploited sources. Key points • The highest binding capacity for selected REEs was registered for P. patens. • The highest biosorption was found for Au and the biomass of the examined moss. • Biosorption capacities of P. patens seem to depend on the cultivation mode.

“…However, at pH values greater than 6.0, depending upon the ion concentration, the precipitation of lanthanides commences . Apart from this, changes in the rate of the biosorption of lanthanides according to the pH value was reported for strains of Curtobacterium sp., Bacillus subtilis , B. pumilis , and the gram‐negative bacterium, P. putida . This finding suggested that the cell wall of the gram‐negative bacterium, which has a protective outer membrane, was more resistant to changes in acid–base ambient conditions, and consequently has a higher potential for the biosorption in acidic solutions.…”

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).

“…In the works of Japanese colleagues, at hot springs of Nakafus (Japan) the primary accumulation in pure bacterial cultures, biofilms, and microbial mats of heavy REEs such as Eu, Lu [13] is indicated. A study by Kazak et al [14] reported more significant sorption of heavy REEs with pure cultures of gram-positive bacteria at pH=4. In the table 2 are shown, that alkaline-earth element (Be), some heavy metals (Cu, Co), radioactive Th and REEs, especially light Pr, Nd, La and Ce were strongly concentrated by mats.…”

A small number of ecological-trophic groups of bacteria are noted in saline groundwater’s (30-50 g/L). The obtained data show, that thionic and halophilic forms of saprophytic bacteria dominated, developing in presence of 10% NaCl. Among saprophytic microorganisms, rod-shaped forms of the genus Microbacterium sp. significantly dominated. A significant accumulation of Cu, Co and light REEs by brine microbial communities is shown.
