Metallotolerant

Metallotolerants are extremophile organisms that are able to survive in environments with a high concentration of dissolved heavy metals. They can be found in environments containing arsenic, cadmium, copper, and zinc. Known metallotolerants include Ferroplasma sp. and Cupriavidus metallidurans .

Metallotolerants adapt to their environment by reducing energy loss by excreting less. Many metallotolerant microbes utilise strategies to perform bioremediation, which is seen as a productive way of survival. ^[1]

Sinorhizobium sp. M14 is a metallotolerant bacterium. ^[2] Plants can also survive in highly metallic conditions. ^[3] For example, Noccaea caerulescens is a metallotolerent plant. ^{[4] [5]}
