| Research Abstract |
Fungal odor analysis in early growth stages is important for the conservation of cultural properties. The analytical methods for detecting fungal species and the stage of growth were developed using a distinctive fungal odor[Takeuchi et al, Surf. Interface Anal., 44(6), 694-698(2012)］. Microbial volatile organic compounds were extracted by solid space microextaction, followed by GC/MS analysis. While the fungi were growing, the amount of alcohols, ketones and aldehydes as MVOCs emitted increased. The detection of sesquiterpenes was useful for determining fungal species. The prototype of solid-phase microextraction inlet system available in an ion mobility spectrometer(IMS) was manufactured. Software programs were also made for identifying fungal species by IMS spectra analysis of the odor.
