EVALUATION OF FUNGAL GROWTH (PENICILLIUM GLABRUM) ON A CEILING TILE
Chang*, J.C S., K. K. Foarde, AND D. W. VanOsdell. EVALUATION OF FUNGAL GROWTH (PENICILLIUM GLABRUM) ON A CEILING TILE. Presented at Indoor Air International Workshop, Indoor Air, An Integra- ted Approach, Milton, AUSTRALIA, November 27 - December 01, 1994.
The paper gives results of a study employing static chambers to study the impact of different equilibrium relative humidities (RHs) and moisture conditions on the ability of a new ceiling tile to support fungal growth. Amplification of the mold, Penicillium glabrum, occurred at RHs above 85-90%. Conversely, at lower RHs, decreases were detected. The issue of survival vs. die-off may be important in the control of fungal contamination in building materials.
