“…ex Steud. increased phytoextractive properties compared to the use of only technogenically polluted wastewater from mining enterprises (2) and control (1). The research results presented in Figure 2 indicate that the type of phytoremediant used significantly affects its phytoextractive properties.…”

“…The research results presented in Figure 2 indicate that the type of phytoremediant used significantly affects its phytoextractive properties. Thus, Typha angustifolia L. accumulates significantly more Ce in leaves when using technogenically polluted wastewater from mining enterprises (2) than in the control (1). Inoculation of plants with a consortium of bacteria Bacillus subtilis (3 and 4) inhibited the accumulation of rare earth elements.…”

“…To date, "anthropogenic influence" has become a powerful, determining environmental factor causing "evolutionary changes" in the floras of various regions [1]. It consists in the extraction from the environment, concentration and rearrangement of a wide range of chemical elements and their mineral and organic compounds with secondary dispersion, and the results of anthropogenic impact on phytobiota are especially noticeable in the territories of old industrial regions [2].…”

“…Figure1shows that in the control(1) and under the influence of technogenically polluted wastewater from mining enterprises (2), the distribution of rare earth elements in plant tissues correlates at the level of 0.93, however, plants exposed to technogenically polluted wastewater from mining enterprises are much less degrees accumulate elements. The use of a consortium of Bacillus subtilis bacteria (3 and 4) significantly increases the content of Pr, Nd and Ce.…”

Rare earth elements are not always rare in their total mass, but their concentration in ores is usually so low that this limits the possibility of cost-effective extraction and enrichment for processing and use. At the same time, some rare earth elements accumulate as a by-product of mining ores containing, for example, copper, phosphates and iron. The article presents for the first time data on the accumulation of some rare earth elements in the tissues of phytoremediant plants Phragmites australis (Cav.) Trin. ex Steud., Typha angustifolia L., Typha latifolia L., used for the treatment of technogenically polluted wastewater from mining enterprises. The influence of the symbionts Bacillus subtilis strain DSM 32424, Bacillus amyloliquefaciens strain VKPM V-10642 (DSM 24614), Bacillus amyloliquefaciens strain VKPM V-10643 (DSM 24615), Bacillus subtilis 26D and Azotobacter vinelandii IB-4 on the efficiency of phytoextraction in different species of plants is considered. toremediants. The most effective symbiotic complexes of plants and microorganisms with a high phytoextractive ability to extract some rare earth elements have been identified.
