Composition Analysis of Airborne Microbiota in Outdoor and Indoor Based on Dust Separated by Micro-sized and Nano-sized

Airborne microorganisms are associated with human health and awareness of the important influence nano-sized extracellular vesicles (EVs) on has risen. Thus, we analyzed micro-sized microbes (m-MBs) microbial EVs (n-MEVs) outdoor indoor air through a field study in Seoul, Korea. We conducted 16S rDNA-based metagenomic analysis m-MBs n-MEVs airborne dust (OAD), (IAD), from carpets (IDC). The dominant taxa OAD were altered depending upon outside environment, such as sunny, haze, rainy. Also, IAD IDC changed environment. In addition, there differences microbiome composition diversity between m-MB n-MEV OAD, IAD, IDC. more correlated that IDC, whereas related to those IAD. bioaerosols can be affected by different source according bioaerosol size. Additionally, risk taxa, therefore suggested further for environments is necessary. should included parameters manage quality.
