Rapid discrimination of several fungus species with FTIR spectroscopy and statistical analysis

The classification of fungal species that was based on statistical comparison of their infrared spectra is presented. The results obtained in the present study were compared with the classification hierarchy of kingdom fungi, according to contemporary phylogenetic studies. ir bands originating from the respective groups of chemicals provided a “spectroscopic fingerprint” of the fungal species analyzed. statistical analysis of the spectra was made using a Hierarchical cluster analysis (Hca). The proper wavelength ranges in ir spectrum, crucial for species classification, were selected. The relations between species were evident in the dendrogram diagrams and they followed the systematic classification of the selected fungal species.
