| Abstract [eng] |
The study analyzed the bioaccumulation capacity of the protozoan Tetrahymena thermophila in response to various heavy metal ion concentrations (Zn²⁺, Mo⁶⁺, Cu²⁺, Cr³⁺, Cr⁶⁺, Ni²⁺, Cd²⁺, Pb²⁺). It was determined that under toxic conditions, the protozoa modify their metabolism, exhibit altered movement patterns, change their ion-binding capacity, and display shifts in growth dynamics. A selective breeding method was investigated; however, due to the transmission of toxicity to daughter cells, this approach was abandoned and genetic modification is suggested as an alternative in all future studies. During the study, a filter made from textile waste was developed. Although not biodegradable, the filter demonstrates sustainable secondary use and is intended for disposal through incineration. It was successfully applied for the immobilization of Tetrahymena thermophila and the practical execution of the bioaccumulation process. The sustainability of the filter was supported by the use of Spirulina algae as the primary energy source. This work incorporates strong elements of multidisciplinarity and innovation, opening opportunities for the development of sustainable, passivefiltration-based biotechnological solutions for the removal of heavy metals from the environment. |
