Description :
Heavy metal pollution of soil is a critical problem for the environment as it limits the growth of plants and agriculture crops. Biological Nitrogen (N2) fixation has an important role for the growth of plants. Modern industrialization is the main cause of heavy metal contamination present in the soil in the form of aero soils, residues, strong waste, particulate issue and effluents which is directly dumped into the atmosphere and finally disposed into the soil causing pollution to a great extent. Copper is a micronutrient and an essential trace element required for growth of microorganisms since it is a cofactor for numerous enzymes and an important electron transfer carrier. Increasing levels of copper can be harmful for soil microbiota. This review examines copper concentrations present in the soil by determining the minimal inhibitory concentration (MIC) of soil isolates against Cu. The present review was conducted to potentially isolate N2-fixing bacteria from heavy metal contaminated soil samples as well as examine copper concentrations present in the soil by determining the minimal inhibitory concentration (MIC) of soil isolates against Cu.
