D CHARACTERIZATION OF AIRBORNE FUNGI IN SCIENCE LABORATORY TECHNOLOGY

Airborne fungi are microscopic organisms that disperse through the atmosphere in the form of spores or fragmented hyphae. These spores are naturally present in both indoor and outdoor environments and play essential ecological roles in organic matter decomposition and nutrient recycling. This study examined the Isolation, Identification and Characterization of Airborne Fungi in the Science Laboratory Technology (SLT) classroom and library of the University of Benin. Air samples were collected using the open plate sedimentation method and cultured on Potato Dextrose Agar (PDA). Fungal isolates were identified through macroscopic and microscopic examinations. The species obtained included Aspergillus niger, Aspergillus flavus, Penicillium spp., Mucor spp., Fusarium spp., and Neurospora crassa. The library recorded a higher fungal load than the classroom, likely due to poor ventilation and dust accumulation. The dominance of Mucor and Aspergillus species indicates that humidity and airflow significantly influence indoor fungal growth. This study concludes that classrooms and libraries can serve as reservoirs for airborne spores, and recommends improved ventilation, regular cleaning, and routine monitoring to ensure a
healthier learning environment and protect educational materials.
