The advancement of industry and agriculture, combined with population growth, has raised numerous concerns within the scientific community regarding the state of environmental contamination and the scarcity of natural resources. A significant pollution issue has evolved from the ongoing xenobiotic and recalcitrant compound contamination of the environment. Due to their toxicity and inability to degrade, numerous contaminants, including heavy metals, polychlorinated biphenyls, plastics, and different agrochemicals, are prevalent in the environment. Bioremediation holds a prominent role in removal of persistent pollutants from the environment. Novel bioremediation technologies are harnessed as the conventional methods of bioremediation have limitations. Recently, microbial biomass has been emphasized as an alternate approach for decontaminating environment compartments due to its distinct qualities that can be used for human advantage. Microbial bioremediation is an environmental friendly method to reduce environmental contamination brought on by various contaminants, including heavy metals, organic pollutants, and oil spills. The use of microorganisms to remove, convert, or alter environmental pollutants into harmless substances from various environmental matrices is now developing into a promising technique, attracting interest from both the scientific community and entrepreneurs. The ability to reduce environmental toxins is being made possible by the ongoing development of novel microbial bioremediation techniques. These developments have the potential to alleviate pollution issues while fostering ecological resilience and environmental sustainability. Hence, this chapter aims to give a brief summary on the most recent approaches and developments in microbial bioremediation methods that are intended to lessen the harm that the pollutants do to ecosystems.
