Surface-enhanced Raman spectroscopy (SERS) was employed to detect the biochemical changes in Gordonia-HS126-4N bacterial strain mediated by exposure to 4,6-dimethyldibenzothiophene. SERS has revealed significant changes induced in the bacterial cells after exposure to a compound, confirming its potential for evaluating their desulfurization capability. Principal component analysis (PCA) and partial least squares–discriminant analysis (PLS-DA) were demonstrated to be effective tools for comparison of the exposed and unexposed bacterial strains. PCA was used for differentiating the SERS spectra of unexposed and exposed Gordonia-HS126-4N. PLS-DA was employed on SERS spectra for the discrimination of the unexposed and exposed bacterial strains with 87% specificity, 88% sensitivity, 89% accuracy, and the value of area under the receiver operating characteristics curve (AUROC) of 0.78, which indicates the excellent performance of the chemometric model.
