Multiple choice

Which of the following techniques is commonly used to enhance the bioremediation of petroleum hydrocarbons?

  1. Bioaugmentation

  2. Biostimulation

  3. Landfarming

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bioaugmentation, biostimulation, and landfarming are commonly used techniques to enhance the bioremediation of petroleum hydrocarbons. Bioaugmentation involves the introduction of hydrocarbon-degrading microorganisms into the contaminated site, while biostimulation involves the addition of nutrients or other amendments to stimulate the growth of indigenous microorganisms. Landfarming involves spreading the contaminated soil over a large area to promote natural biodegradation.

Multiple choice

Which of the following is a potential limitation of using genetically engineered microorganisms for bioremediation?

  1. They may have unintended ecological consequences
