The use of bacteria to degrade heavy soil metal concentrations and boost plant tolerance to elevated metal levels has significant ecological and financial benefits. Soil contaminated with heavy metals may cause a variety of problems. First, the soil respiration is affected by the heavy metal content because of the way it affects the respiration, metabolism (the metabolic entropy response), and activity of soil microbes. There is less organic carbon converted to bio-carbon and higher microbial metabolic entropy in metal-contaminated soil. Last but not least, heavy metals may be absorbed by seeds, leading to physiological dysfunction and malnutrition in the developing plant. Having an excess of metals in the body might be dangerous. Therefore, the use of bacterial which use various mechanism to degrade heavy metals is the best approach of this paper in getting reed of the heavy metals in soil.
