The research introduced about the emission patterns of MVOCs as fungal growth processes. The relationships between the growth of the fungal thread and sporule, and MVOC emitting rates were investigated. Fungi could not be visible, however invisible fungi emit MVOCs such as acetaldehyde, acetone,,-methyl-+- propanol and etc. When the fungi grew with their sporule and changed their color, other MVOCs such as --Methyl-+-butanol, + -Octen---ol were emitted until about, weeks. Then as stopping growing, MVOC emissions decreased. Key words : Volatile organic compounds, Fungi, Indoor air quality
