HEAVY METAL RESISTANT BACTERIA IN RHIZOSPHERIC SOIL: A REVIEWIndrani Gogoi and Kalyan DasAbstract Concern over heavy metal contamination is a common issue related to soil health. Soil is an excellent habitat for various microbes. Microbial activities in soil are negatively impacted by high concentrations of heavy metals. The physico-chemical changes of soil microorganisms are recognized as a sensitive indicator to assess soil quality. Some plants can absorb metals, and eventually, through food chains, humans and other animals are exposed to them. As a result of ongoing exposure to heavy metals, the rhizospheric bacteria of metal accumulator plants develop intrinsic or extrinsic resistance mechanisms. Through their critical contribution to metal detoxification, these resistance mechanisms either directly or indirectly support plant growth and development. Therefore, it is crucial to look into the correct mechanisms of plantrhizospheric microbe interaction in metal-contaminated soils. The current review sought to highlight the metal-resistant bacterial communities in rhizospheric soils and their part in plant health management. |
