Detailed explanation-1: -Bioremediation was developed as a cost-efficient, environment-friendly, and sustainable option for hazardous waste treatment (Azubuike et al., 2016; Chaturvedi et al., 2021). It involves applying some bacteria and other microorganisms to extract or degrade inorganic and organic contaminants.
Detailed explanation-2: -Bioremediation broadly refers to any process wherein a biological system (typically bacteria, microalgae, fungi, and plants), living or dead, is employed for removing environmental pollutants from air, water, soil, flue gasses, industrial effluents etc., in natural or artificial settings.
Detailed explanation-3: -Bioremediation refers to the use of living organisms to remove contaminants, pollutants, or unwanted substances from soil or water (FAO, 2001).
Detailed explanation-4: -“Bioremediation is a waste management technique that includes the use of living organisms to eradicate or neutralize pollutants from a contaminated site.” “Bioremediation is a ‘treatment techniques’ that uses naturally occurring organisms to break down harmful materials into less toxic or non-toxic materials.”
Detailed explanation-5: -Bioremediation is the use of microbes to clean up contaminated soil and groundwater. Microbes are very small organisms, such as bacteria, that live naturally in the environment. Bioremediation stimulates the growth of certain microbes that use contaminants as a source of food and energy.
