Sumario:Environmental pollution by heavy metals is largely the result of human activities, particularly the mining industry. The extraction and processing of minerals generates large quantities of toxic compounds that affect the quality of the environment and the health of living beings. For a long time, efforts have been made to develop strategies to remove heavy metals from the environment to mitigate their toxicity. Among these strategies, those that use organisms such as plants, fungi, algae, and bacteria stand out, since they are more efficient, do not generate secondary waste and are not costly. These organisms must have the capacity to grow in high concentrations of metals in order to be used in remediation. In this work seeks to show the different mechanisms used by bacteria for the removal of metals, as well as the metals that can be eliminated.
