Extremophile organism that tolerates high concentrations of dissolved heavy metals
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]
