Through human activities, a lot of toxic substance have been initiated into our environment like persistent organic pollutants, toxic metals, soil contamination with petroleum hydrocarbons and chemical pesticides fertilizers, which is a planetary problem affecting human and ecology health. Restoring our world in a sustainable way is the key priority for all. We need to remove and mitigate our pollution and microbes might be our answer.
Microbes are better known for their fundamental role to breaking down complex organic compound and absorbing inorganic substance into our soil ecosystem, making nutrients available for plant uptake leading to increased productivity and healthy soils. Presently, microbes can also be used to clean up and mitigate pollution.
Through a process known as “bioremediation” microbes are used to reduce pollution through degrading, breaking down, transforming and removing pollutants from the non-toxic substance such as soil and water. Bioremediation techniques when merged with sustainable practices like use of renewable sources instead of fossil fuel energy will emanate better social, environment and economy benefits.
Bioremediation takes place when microbes comes in contact with contaminates of soil, groundwater and surface. In the process microbes’ secrets enzymes that breaks down contaminants into small compounds that they can consume and use them as source of food and energy. In return, of digestion process microbes releases carbon dioxide, water and non-harmful amino acids. In ideal environment conditions like surface ph., temperature, availability of moisture and sufficient food supply, microbes reproduce and increase in number promoting the removal of additional contaminants and the cycle replicates until all the food source is diminished.
Bioremediation can be modified to the need of the polluted area in question, and certain microbes needed to break down the contaminants encouraged by selecting the limiting factors needed to stimulate their growth.
Pollution is a threat to our health and our environment, affecting the sustainability of our planet earth and damaging our soil hence reducing the capacity to produce food to rising population. Bioremediation relies on microbes that poses no threat to people, reduces labor and amount of equipment needed for cleanup making it sustainable to remove and mitigate further pollution. By this, we create clean air, water and healthy fertile soil to coming generations.
As our realization on the importance of microbial reactions, grow our capacity to utilize them to our advantage increases.
