Soil Microbe-Mediated Bioremediation: Mechanisms and Applications in Soil Science

Bioremediation is a prominent and novel technology among decontamination studies because of its economic practicability, enhanced proficiency, and environmental friendliness. The continuously deteriorating environment due to pollutants was taken care of by the use of various sustainable microbial processes. It is a process that uses microorganisms like bacteria and fungi, green plants, or their enzymes to restore the natural environment altered by contaminants to its native condition. Contaminant compounds are altered by microorganisms through reactions that come off as a part of their metabolic processes. Bioremediation technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the pollutants at the site, while ex situ bioremediation involves the elimination of the pollutants to be treated elsewhere. This chapter deals with several aspects, such as the detailed description of bioremediation, factors of bioremediation, the role of microorganisms in bioremediation, different microbial processes and mechanisms involved in the remediation of contaminants by microorganisms, and types of bioremediation technologies such as bioventing, land farming, bioreactors, composting, bioaugmentation, biofiltration, and bio-stimulation.
