Types of Bioremediation

The different types of bioremediation are explained below:

Biostimulation

In this technique, the bacteria is stimulated to initiate the process. For this, the contaminated soil is first mixed with the required nutrients including other important components either in the form of liquid or gas. These components will stimulate the growth of microbes resulting in efficient and quick removal of the contaminants.

Bioaugmentation

In some cases, microorganisms are required to extract the contaminants from the contaminated site. An example of sewage water can be taken. In such cases, the bioaugmentation technique is used. The only disadvantage here is that it becomes impossible to control the growth of microorganisms at that site in the process of removing a particular contaminant.

Intrinsic Bioremediation

This process is most effective for the waste treatment of soil and water. The process of intrinsic bioremediation is mostly used in waste treatment of underground places like underground water tanks, underground petroleum tanks, etc.

At these sites, it becomes difficult to detect a leakage and due to this contaminants and toxins can find their way to enter through these leaks and contaminate the water, petrol, etc. So through this, it can be understood that only microorganisms can remove the contaminants at these sites and thus clean the tanks.

Bioremediation refers to a biochemical process that makes use of microbes in an eco-friendly way. It is used as an alternative to the conventional waste management system, which involves using some chemicals that are harmful to the ecosystem.

There are different types of bioremediation depending on the substance which is to be degraded. But depending on different factors, bioremediation is of different types. Even though this is a very crucial technique still 100% contamination cannot be cleared by it. In this article, we will discuss Bioremediation – types and examples.
