Recent advancements in microbial-assisted remediation strategies for toxic contaminants

Abstract

Continuous rising anthropogenic sources such as industrialization caused environmental contamination and health hazards. Toxic pollutants deposition in water and soil streams is now recognized as a severe environmental issue that has a variety of negative consequences on the health of plants and animals. Approximately 300–400 million tons of industrial wastewater containing toxic materials such asheavy metals, hydrocarbons, and radioactive elements are released into the environment each year without proper treatment. Such dangerous chemicals have mutagenic and cancerous impacts on human health, wildlife, and vegetation when they are released into the environment. Several innovative technical approaches are currently being explored to speed up the clean-up of polluted sites. Through the all-encompassing activity of microbes, remediation is heavily involved in the deterioration, removal, immobilization, or detoxification of various chemical wastes and environment. Microbes may thrive in a wide range of conditions and produce metabolites that degrade and convert pollutants, allowing contaminated facilities to be naturally rejuvenated. Microorganisms have a range of metals sequestration capabilities that help them to have higher metals biosorption abilities.The focus of this article will be on a microbiological technique that is reportedly employed in pollution monitoring to reduce pollutant concentrations. We investigate the prerequisites for analysing scientific data in order to construct synthetic biological models of microbial bioremediation in this review, which includes studying the prerequisites for developing synthetic biological models of microbial bioremediation. In addition, the importance of microbial technology in bioremediation for the future has been described.
