After the investigation of fungal and bacterial growth in unit weight of dust samples collected from duct of air-conditioning systems, we found the counted number of colonies was higher than bacterial. Also, three fungal genera isolated from dust samples proliferated rapidly on broth media made of sampled dust. Three test media (No.8, No.12 test powder and hemicellulose) which are substitutes for maior components of dust (sand, soot, and fiber trash respectively) were made to conduct further investigation for fungal and bacterial growth. Three different fungi identified to genus's level and six different fungi identi fied to species level were innoculated on each test medium. Each fungus showed rapid proliferation on test media. On the contrary, two different bacteria innocultated on the sme modia didn't proliferate at all.
