Abstract

Environmental and forensic scientists along with
industrial institutions are exploring more use of IR spectroscopy together with
chemometrics for various applications. It can be used to detect the pollution
level of the environment and to screen the promising microbial isolates to be
applied for the bioremediation. Food, petroleum, drug industries and tire
factories apply this technique both in their laboratories and in field for
analytical purposes. IR spectroscopy has also gained attention in criminology
due to its high sensitivity and speed in the analysis of evidential material.
Identity and gender of a victim, narcotic drug abuse, toxins and explosives can be identified using this
technique coupled to chemometrics. Analysis of body fluids is also possible for
the identification of forensic species, which is a crucial part of
investigation at a crime scene. Moreover, it can be administered for robust and
efficient identification of old skeletal fossils or fragmented anatomical
remnants, which is a difficult task for forensic specialists. It is known that
biological agents such as bacteria and viruses can be exploited in bioterrorist
acts or germ warfare. Rapid discrimination of these microbial species are
achieved using IR based identification methods in forensic studies. In our
study, we applied IR coupled chemometrics for the determination of heavy metal
resistant environmental bacterial species. Although we did not study the
forensic features of these bacteria directly, knowing the environmental
microbial profile can help to find the place where the crime took place and to
reveal the timeframe in good confidence.
