• Bioremediation is a process of removing or degrading the toxic pollutant from the environment by using microorganism .

• commonly used micro organisms are, Pseudomonas,Flavobacterium,Arthrobacter, and Azotobacter

• Bioremediation focuses on different sources they are called as different names. plant------------- phytoremediation fungi------------- mycoremediation

Bioremediation

•Degradation or Transformation of a substance into new compounds through biochemical reactions or the actions of microorganisms such as bacteria.

GMOs

The genetically engineered micro organism (GEMs)enhance the ability of degrading the contaminants. It is also said to be as a “bioaugmentation”

The bacterium Deinococcus radiodurans(the most radioresistant organism known) has been modified to consume and digest toluene and ionic mercury from highly radioactive nuclear waste.
