Here, flow cytometry with fluorochrome (FCM/FL) was applied to evaluate the sampling performance of impingement (AGI-30 all-glass impinger) and filtration (track-etched polycarbonate filter) with different types of fluorescent dye staining (cell membrane integrity and metabolism) and then compared with a traditional culture method (culturability). Two bacterial aerosols (Escherichia coli and endospores of Bacillus subtilis) and two fungal aerosols (Candida famata and Penicillium citrinum spores) were studied. The bioaerosol viability during the sampling processes was highly influenced by bioaerosol characteristics (hardy or fragile), as well as by the fluorescent dyes with different physiological mechanisms. For better viability of the sampled bioaerosol, the impinger was superior to the filter. Moreover, it was found that sampling stress from filtration had more influence on the bioaerosol metabolism mechanism than cell membrane integrity. Furthermore, the differences between cell membrane integrity and the metabolism by sampling stress were found related to the bioaerosol species.application/pdf242248 bytesapplication/pdfzh-TW國立臺灣大學公共衛生學院環境衛生研究所生物氣膠採樣效率流式細胞 儀bioaerosolsampling efficiencyflowcytometry螢光顯微鏡、流式細胞儀與定量PCR用於生物氣膠之分析(2/3)SAMPLING PERFORMANCE FOR BIOAEROSOLS BY FLOW CYTOMETRY WITH FLUOROCHROMEreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/4886/1/932320B002050.pdf
