| Outline of Final Research Achievements |
Physiological roles of microbial volatile organic compounds (MVOCs) emitted from fungi remain to be unclear. We clarified here the function of MVOCs in terms of their activities on the fungal growth. Application of the co-culturing system in a growth chamber allowed free gas or volatile exchange between a releaser and a receiver, or between the colonies of different growth stage of the same species.
Solid phase microextraction-gas chromatography/mass spectrometry (GC/MS) revealed MVOCs of Aspergillus fumigatus and Fusarium solani. Quantitative analysis of MVOC by GC/MS revealed hexanal from F. solani and heptanal from A. fumigatus working as the self-inhibitor of each growth. Benzaldehyde, released from the colonies of F. solani, played as an allelochemical inhibitor against those of A. fumigatus.
