Question

Which of these best describes a use of a biostimulation?

Answer 1

Answer;

B. To clean up oil spills using natural bacteria.

Explanation;

-Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation. This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon, which are otherwise available in quantities low enough to constrain microbial activity

-It is a type of natural remediation that can improve pollutant degradation by optimizing conditions such as aeration, addition of nutrients, pH and temperature control. It can be considered as an appropriate remediation technique for petroleum pollutants removal in soil and requires the evaluation of both the intrinsic degradation capacities of the autochthonous microflora and the environmental parameters involved in the kinetics of the in situ process.

Answer 2

It doesn't show the choices but, Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation.
