The fluorescent percentage of spores was found to decrease for both fungal genera as they aged. The study demonstrated an increase in aerodynamic diameter for fungal spores under investigation (Aspergillus niger and Penicillium species) over a period of time. The UVAPS was used to detect and measure auto-fluorescing biomolecules such as riboflavin and nicotinamide adenine dinucleotide phosphate (NAD(P)H) present in the released fungal spores. Fungal spores were released by blowing the surface of the culture colonies with continuous filtered flow air. The second objective was to investigate the change of fungal spore size during this period, which may be of use as a co-factor in this differentiation. This outcome was achieved through the measurement of fungal spore fluorescent percentage and fluorescent intensity throughout a period of culturing time (three weeks), and the study of their fluorescent percentage as a function of exposure to air currents. The UVAPS response was investigated as a function of fungal age and the frequency of air current that their colonies exposure to. The first was the assessment of the response of the Ultraviolet Aerodynamic Particle Sizer Spectrometer (UVAPS) for two different fungal spore species. ![]()
