Polar areas are not exempt from anthropogenic pollution. Heavy metals have been detected in Arctic and Antarctic lakes. Bacteria, at the base of food web, can possess ability to adsorb or immobilize heavy environment reduce their concentration water column. However, several gaps exist our knowledge bacterial tolerance polar systems, especially metal-tolerant bacteria lacustrine sediments were selectively enriched subsequently isolated identified. Their growth increasing concentrations different (iron, copper, mercury) was evaluated. Selected isolates tested for sequestration iron mercury. A total 101 obtained metal-enriched cultures. Gammaproteobacteria Actinomycetota most abundant enrichments, respectively. Iron tolerated metal. Mercury sequestered by up 14.2 13.4%, The results this study contribute understanding cold environments potential use biotechnological applications.
