How bacteria are used in bio remediation of polluted soil?
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. The hydrocarbon loses electrons and is oxidized while oxygen gains electrons and is reduced.
What is the difference between in situ and ex-situ bioremediation?
In in situ bioremediation, contaminants are treated at the same site using biological systems. In ex situ bioremediation, contaminants are treated in some other place from the original site. Bioremediation processes are cost effective, safe and nature-based methods over the chemical and physical methods.
What is bioremediation essay?
Bioremediation is the technique of using living organisms to clean up contamination in land and water is called bioremediation. Bioremediation uses bacteria and fungi to break down oil. Nitrates or fertilizers are added to the spill to provide nutrients to quicken the growth of the bacteria and fungi.
What best describes ex situ treatment?
Ex situ techniques involves the treatment of contaminated soil, away from the polluted site. Ex situ techniques involve land farming, biopile, windrow, soil washing, composting, bioreactor, ion exchange, adsorption/absorption, pyrolysis and ultrasound technology.
How does in situ bioremediation differ from ex situ bioremediation?
In in situ bioremediation, contaminants are treated at the same site using biological systems. In ex situ bioremediation, contaminants are treated in some other place from the original site. This is the key difference between in situ and ex situ bioremediation.
What are the 3 types of bioremediation?
Some of the most common types of bioremediation are microbial bioremediation, phytoremediation, and mycoremediation. However, the word bioremediation has evolved in recent years to include biohazard removal and crime scene cleanup services.
