Abstract: | Buildings with poor indoor air quality (IAQ) frequently have many areas with surface fungal contamination. Studies have demonstrated
that certain fungal genera (e.g., Cladosporium, Penicillium, and Stachybotrys) are able to grow on building materials such as wallpaper, drywall, and ceiling tiles, particularly after water damage has
occurred. Due to the increasing awareness of sick building syndrome (SBS), it has become essential to identify building materials
that prevent the interior growth of fungi. The objective of this study was to identify building materials that would not support
the growth of certain fungal genera, regardless of whether an external food source was made available. The growth of three
fungal genera (Cladosporium, Penicillium, and Stachybotrys) was evaluated on cellulose-containing ceiling tile (CCT) and inorganic ceiling tile (ICT). Both types of ceiling tile were
exposed to environmental conditions which can occur inside a building. Our results show that ICT did not support the growth
of these three fungal genera while CCT did. Our data demonstrate that ICT could serve as an ideal replacement for CCT.
