ABSTRACT
The application of microbiology to environmental forensic investigations includes a range of subdisciplines, including microbial physiology, molecular microbial ecology, and microbial biochemistry. Microbial forensics employs a range of techniques to trace a contaminant through the environment using a microbial marker. Many of these techniques, such as selective isolation
