LIFE SCIENCE

Detailed explanation-1: -This process is known as bioaugmentation. Bioremediation technique in which natural or genetically engineered bacteria with unique metabolic profiles are used to treat sewage or contaminated water or soil.

Detailed explanation-2: -During bioremediation, microbes utilize chemical contaminants in the soil as an energy source and, through oxidation-reduction reactions, metabolize the target contaminant into useable energy for microbes.

Detailed explanation-3: -Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria to decontaminate affected areas. It is used in the removal of contaminants, pollutants, and toxins from soil, water, and other environments.

Detailed explanation-4: -Bio-venting is an in situ remediation technique that uses microorganisms to degrade organic constituents adsorbed on soils [17]. This technique involves regulated stimulation of airflow for increasing oxygen to unsaturated zone for enhances the bioremediation, by increasing activities of indigenous microbes.

Detailed explanation-5: -Bioremediation is an eco-friendly process of the degradation of toxic pollutants into nontoxic or less hazardous substances mediated by microbial enzymes. Biodegradation of various hazardous pollutants through the application of different enzymes from bacteria and fungi have been widely studied.
