In the case of bioaugmentation, microbes are introduced into the environment to clean up and absorb a certain pollutant. My question is how is that microbe then removed from the environment once it performs its function?
Usually you have to introduce conditions which hinder multiplication of the microbe such as altering the pH and emperature. This is hard to achieve in a large environment, alternatively, you can introduce a recombinant of that microbe which posses a survivability threat to the initial microbe.
