BIODEGRADATION NATURAL PROCESS
BioDegradation natural process
The key difference between biodegradation and bioremediation is that biodegradation is a natural process that occurs in the environment.
On the other hand, bioremediation is an engineered technique applied by humans to clean the environment. Both processes are governed mainly by the microorganisms.
A large number of bacterial and fungal species possess the capability of degrading organic pollutants in the environment.
- Biodegradation is a microorganism-mediated decomposition of organic matter.
- Bioremediation is a technique applied by people to clean up organic matter and other substances. This is done by using microbes with the biodegradation process.
What is BIO Degradation?
The Microorganisms play a key role in the decomposition of organic materials accumulated in the environment. They are the recyclers of nutrients in the soil. Almost all biogeochemical cycles are driven by the indigenous microbial population in the soil. It is the process in which organic compounds are degraded or broken down by the microorganisms and important process that replenishes the environment with nutrients. Microorganisms degrade organic material for their growth and metabolism. As a result, complex organic substances are converted into carbon dioxide and water.
Following are the modes of biodegradation:
- Aerobic biodegradation
- Anaerobic biodegradation
Aerobic biodegradation is done by aerobic microorganisms when an adequate supply of oxygen is available for their activity.
- It is a rapid method that degrades the contaminants completely when compared to anaerobic biodegradation.
Anaerobic biodegradation takes place in the absence of oxygen. Its pathway has four major steps.
-
- Hydrolysis
- Acidogenesis
- Acetogenesis
- Methanogenesis
Organic substances are subjected to anaerobic digestion and converted into carbon dioxide and methane.
