Abstract

Various mixtures of gas-phase, carbon compounds volatile organic compounds (VOCs) produced by fungi are able to diffuse through the atmosphere and soils due to their small size. Fungal VOCs may contribute to a controversial medical diagnosis called ‘sick building syndrome’ or ‘building related illness’ (BRI). Both atopic and normal people exhibit statistically significant physiological and psychological effects when exposed to the odorant compounds emitted by fungi, so it has been hypothesized that these odorants may cause or contribute to BRI. Mold odors are caused by mixtures of VOCs, low molecular mass compounds with high vapor pressure that exist in the gaseous state at room temperature. Different species and strains of filamentous fungi produce different VOC profiles. Approximately 250 VOCs have been identified from fungi where they occur as mixtures of simple hydrocarbons, heterocycles, aldehydes, ketones, alcohols, phenols, thioalcohols, thioesters and derivatives. The diverse functions of fungal VOCs can be developed for use in biotechnological applications for biofuel, biocontrol and mycofumigation. Volatiles represent a new frontier in bioprospecting, and the study of these gas-phase compounds promises the discovery of new products for human exploitation and will generate new hypotheses in fundamental biology
