“…These plant taxa may have originated from local centers of diversity or consumption by local population on a regular basis 32 . Similar interesting findings have also been reported in the Mexico metro and in an urban center in Denver 4 , 28 . The composition and diversity of an aerobiome are strongly linked to the coverage of plantation within a given radius of a site 33 .…”

In this study, we determined the seasonal airborne microbial diversity profiles at SMRT stations by sequencing the 16S rRNA and ITS. Particulate matter samples were collected from air purifiers installed in the platform area of the SMRT subway stations. Three stations that included the most crowded one were selected for the sampling. The sampling was done at each season during 2019. After extracting the total DNA from all seasonal samples, PCR was performed with Illumina overhang adapter primers for the V3–V4 region of the 16S rRNA gene and ITS2 region of the ITS gene. The amplified products were further purified, and sequencing libraries were made. Sequencing was carried with the Illumina Miseq Sequencing system (Illumina, USA) followed by in-depth diversity analyses. The elemental composition of the particulate matter samples collected from the different subway stations were obtained using a WD-XRF spectrometer. The SMRT microbiome showed extensive taxonomic diversity with the most common bacterial genera at the subway stations associated with the skin. Overall, the stations included in this study harbored different phylogenetic communities based on α- and β-diversity comparisons. Microbial assemblages also varied depending upon the season in which the samples were taken and the station. Major elements present at the subway stations were from aerosols generated between wheels and brake cushions and between the catenaries and the pantographs. This study shows that the microbial composition of the SMRT subway stations comes from a diverse combination of environmental and human sources, the season and the lifestyle of commuters.

“…Previously reported numbers of cells found in a defined volume of air are based either on cultivation (colony-forming units; CFUs) or are estimated by amplified ribosomal molecular markers (2, 7). Furthermore, research into airborne microbial organisms is predominantly carried out in countries located within temperate climate zones or as global surveys with varying geographic and climatic parameters (8–10).…”

SignificanceThis manuscript describes a precise diel cycle carried out by airborne microbiota in the tropics. 795 metagenomes from air samples taken from a single site show that fungi, bacteria, and plants all adhere to a specific timing for their presence in the near-surface atmosphere. The airborne community composition thereby shows an unexpected robustness, with the majority of the dynamics in taxa composition occurring within 24 h, but not across days, weeks, or months. Environmental parameters are the main drivers for the observed phenomenon, with temperature being the most important one.

“…[58][59][60] A majority of studies assessed overall microbial communities through sequencing, typically employing 16S rRNA. Of these 67 studies, nine classified the population taxonomy to order level, [61][62][63][64][65][66][67][68] eight classified to family level, 69-74 37 classified to genus, 51,64,75-109 12 classified to species 28,54,59,83,98,[110][111][112][113][114][115][116][117][118] and only one identified a strain-specific 119 species (Figure 3). When classified to order or family,…”
