Biomarker

Definition

A biomarker is a measurable indicator of biological processes, conditions, or responses to a treatment. In the context of bioremediation, biomarkers are essential for identifying and monitoring microbial activity, as they can indicate the presence of specific microorganisms or their metabolic byproducts that can degrade pollutants. Understanding these indicators can help assess the effectiveness of bioremediation strategies and track environmental recovery.
