Bioremediation Mcqs

Bioremediation is a process of treating contaminated media such as subsurface material, soil, and water by altering environmental conditions to encourage microbial growth and degrade pollutants. It is an economical and sustainable alternative to other remediation techniques. A similar process, biological treatment, is used to treat industrial and wastewater as well as solid wastes.
