Balycheva, Daria Sergeevna Blaginina, Anastasiia Andreevna Lishaev, Vyacheslav Nikolaevich Kapranov, Sergey Victorovich Miroshnichenko, Ekaterina Sergeevna Zheleznova, Svetlana Nikolaevna Simokon, Mikhail Vitalievich Ryabushko, Vitaliy Ivanovich Bioaccumulation by diatoms, as the first stage of biomineralisation, has been widely studied for various metals, such as cadmium, copper, zinc, aluminium, gold, silver, etc. However, despite the fact that the mining and utilization of rare earth elements (REEs) are currently increasing, there is almost no data on their bioaccumulation by diatoms. Therefore, the aim of this study was to determine the ability of diatoms to bioaccumulate REEs by the example of lanthanum (La), and to compare this ability for two marine diatoms and . As a result of experiments on the cultivation of diatoms in nutrient media supplemented with La at concentrations of 10 mg·L and 50 mg·L, energy-dispersive X-ray spectroscopy revealed the ability of diatoms to bioadsorb La on their frustule surface, as a first stage of its bioaccumulation. The high concentration of La (50 mg·L) has a noticeable visual effect on the morphofunctional state of diatoms and causes a decrease in the rate of accumulation. The low concentration (10 mg·L) promotes the hyperaccumulation of La by the diatom biomass as a whole, including both bioadsorption and bioabsorption within the cells. This resulted in an increase in La concentration in the biomass by nearly 2000-fold in (6.06 mg·g) and by 1000-fold in (6.90 mg·g). The results on La bioaccumulation by diatoms are significant for advancing methods to remediate aquatic environments contaminated with rare earth elements and for the bioindication purposes. |
