Bioremediation: Using Nature for a Clean Environment

Pollution has been a problem for centuries, damaging much of the Earth and the population living in it. From the smoke of industrial factories, to the agricultural runoff in rivers, it has been silently lowering the quality of life for many. While numerous solutions have been invented to stop this problem, most are either short-lived or too expensive to consistently create and spread around the globe. However, what if there was an answer, laying right in Mother Nature herself?

What is Bioremediation? 

Bioremediation is an environmental cleaning process that utilizes living organisms like fungi and plants to degrade or detoxify contaminated air, water or soil. Bioremediation typically is used to safely convert hazardous toxic wastes into safe byproducts like water and carbon dioxide. Bioremediation’s core works by tapping into the natural metabolic process of living organisms and giving them a boost depending on necessity. The true motive is to decontaminate the environment and digest contaminants such as petroleum, pesticides, and industrial solvents to clean the Earth, as well as sustaining the planet.

  Bioremediation is a lot more cost-effective and offers a more permanent solution than soil excavation and incineration as it destroys just the pollutant rather than transferring the pollutant from one area to another or ruining an environment to destroy the pollutant. 

Methods of Bioremediation Used Today

 There are three commonly used methods of Bioremediation used today: Biostimulation, Bioaugmentation and Natural Attenuation. 

Biostimulation which is adding nutrients such as nitrogen or phosphorus or electron donors to a contaminated site to help stimulate activity and growth of the already present microbes native to that site. Biostimulation is typically the second most used as it is used when natural attenuation is too slow or not keeping up with the necessary timeline of the natural cleaning process.

  Natural attenuation is the natural process of breaking down contaminated areas over time with no human intervention which is still the first method used even though there are faster ways, as the natural way of life is hard to beat.

  Lastly, is bioaugmentation which is introducing specific strains of laboratory-grow or cultured micro-organisms to a polluted site where the necessary microbes are missing or insufficient in their numbers. There is research on bioaugmentation about its potential in harming if too many foreign microbes end up in an area it could cause disruptions to local ecosystems, acting as one of the reasons why it is not commonly used. Another reason why it is used as a last resort out of the three methods is the fact that introduced microorganisms could have a hard time adapting to the new environment or might be outcompeted by native species currently present in such areas. 

Overall, these methods of bioremediation essentially all try to clean up our environment but the amount of time is dependent on the specific method used. Biotechnology is an essential item to speeding up many of our processes in life and bioremediation’s biostimulation and bioaugmentation are only some of many processes that biotechnology is necessary in.
