2. Types of bioremediation.
3. Factors affecting Bioremediation.
4. Advantages and Disadvantages of Bioremediation.
5. Summary.
6. Conclusion

3.  Bioremediation literally means the elimination of something undesirable from the
environment by applying biological sources such as plants and microbes or the
substances obtained from them.
 Though it is a naturally occurring process, many interventions can be introduced
to make it fast, efficient, and specific to degrade the pollutants at contaminated
sites
 Bioremediation uses either naturally occurring or deliberately induced
microorganisms to degrade or reduce environmental pollutants in order to clean
contaminated sites

5. Process of phytoremediation

6. Factors affecting Bioremediation

7. Advantages of Bioremediation
 Bioremediation is a natural process and is therefore perceived
by the public.
 Bioremediation is useful for the complete destruction of a wide
variety of contaminants.
 Bioremediation can often be carried out on site, often without
causing a major disruption of normal activities.
 Bioremediation can prove less expensive than other
technologies that are used for cleanup of hazardous waste.

8.  Bioremediation is limited to those compounds that are
biodegradable
Concerns about the products of biodegradation: toxic than
the parent compound.
 Biological processes are often highly specific.
It is difficult to deduce from bench and pilot-scale studies to
full scale field operations.
 Bioremediation often takes longer than other treatments
options.

9. Bioremediation is a eco – friendly technology.
 It is effective process.
Bioremediation uses naturally occurring organisms to breakdown
hazardous substance into less toxic or non toxic substance.
Technology generally classified as in situ and ex situ Bioremediation.
In situ Bioremediation involves removal contaminated material at the
site.
And Ex situ bioremediation involves the removal of the contaminated
material to be treated elsewhere.
