Microbial remediation of heavy metal (HM) pollution is a promising approach for restoring soil health and reducing toxic effects. This review discusses the mechanisms and future prospects of microbial-mediated remediation of HMs, focusing on bacteria, fungi, and algae. Microbes can bio-sorb, bio-accumulate, bio-leach, bio-transform, and bio-volatilize HMs, reducing their availability and toxicity. Recent advancements in bioremediation, including genetic engineering and bioinformatics, have enhanced the efficiency of microbial remediation. However, challenges remain, such as the need for more effective microbial strains and understanding of environmental factors affecting bioremediation. The review highlights the role of various microbes in remediating soils contaminated with HMs like Cd, Cr, Pb, and As. It also discusses the importance of soil pH, temperature, and organic matter in influencing microbial activity. The study emphasizes the potential of microbial remediation as an environmentally friendly and cost-effective solution for HMs pollution, with ongoing research aimed at improving its effectiveness.Microbial remediation of heavy metal (HM) pollution is a promising approach for restoring soil health and reducing toxic effects.
