Description
Summary:In our study, headspace solid-phase microextraction coupled with gas chromatography–mass spectrometry (HS-SPME-GC-MS) technique was used to analyse microbial volatile organic compounds (MVOC’s) of a mushroom disease-related microorganism: Trichoderma aggressivum. Its volatile metabolite markers were monitored and then identified. To make reliable identification results, different manual correction steps were implemented into the evaluation process (depending on the compound intensity or on the rate of compound coelucion). Identification steps were the follows: background subtraction then manual deconvolution. In some cases, compounds’ molecular ion appeared on the mass spectra, which molecular ion’s m/z value was also used for the identification. Moreover retention index (RI) of the evaluated compound was also calculated then compared to the RI values found in the literature and WebBooks.
