Forensic Pedology: From Soil Trace Evidence to Courtroom

The growing field of soil microbial forensics provides the legal answer to how microorganisms play a crucial role in criminal investigations. It is an advanced crossdisciplinary science capable of offering significant physical evidence with considerable interest in criminal investigations, environmental crime, and counterterrorism. Microbial forensics of soil consists of different techniques to identify and evaluate microbial abundance, their complexity, and their interaction with soil and surrounding objects. The present review highlights various microbial analysis techniques such as Terminal restriction fragment length polymorphism, Temperature/Denaturing Gradient Gel Electrophoresis, Amplified Ribosomal DNA Restriction Analysis, Length Heterogeneity PCR, Phospholipid-derived fatty acids, Fluorescence in situ hybridization, Stable-isotope probing and metagenomics using nextgeneration sequencing. This article also summarises the challenges faced in soil microbial forensics, various statistical approaches, reference databases commonly used in forensic soil studies, and different methodological approaches used in forensic laboratories. Literature was studied using various online bibliographic databases like Google Scholar, Web of Science, Pub Med, Scopus, and several other search engines. Conclusive evidence generated by this paper signifies the importance of soil microbes to assist forensic scientists and researchers in selecting adequate methods to differentiate soil samples. The present comparative study concluded that targeted molecular analysis of microbes as a forensic soil typing tool has a lot of potential and should be investigated further.
