Fungal Odor Analysis for Conservation of Cultural Properties

Abstract

Fungal odor analysis in early stages is important for the conservation of cultural properties. We developed a technique for detecting fungal species and the stage of growth by [Takeuchi et al, Surf. Interface Anal., 44（6）, 694-698,（2012）] . Microbial volatile organic compounds are 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.
