Metagenomic Analysis of the Outdoor Dust Microbiomes: A Case Study from Abu Dhabi, UAE

Outdoor dust covers a shattered range of microbial agents from land over transportation, human flora, which includes pathogen and commensals, airborne the environment. Dust aerosols are rich in bacterial communities that have major impact on health living environments. In this study, outdoor samples roadside barricades, safety walls, fences (18 samples) were collected Abu Dhabi, UAE diversity was assessed through 16S rRNA amplicon next generation sequencing approach. Clean data HiSeq produced 1,099,892 total reads pairs for 18 samples. For all samples, taxonomic classifications assigned to OTUs (operational units) representative sequence using Ribosomal Database Project database. Analysis such as alpha diversity, beta differential species analysis, relative abundance performed clustering functional profile heat map obtained by bioinformatics tools. A 2814 identified those with coverage more than 99%. phylum, had most groups Actinobacteria, Proteobacteria, Firmicutes, Bacteroidetes. Twelve Propionibacteria acnes mainly found RD16 RD3. Major bacteria acnes, Bacillus persicus, Staphylococcus captis Most Streptococcus mitis, capitis. Nafulsella turpanensis Enhydrobacter aerosaccus part normal microbes skin. Salinimicrobium sp., alkalisediminis, persicus halophilic sediments. The clustered vertical horizontal classification, represents relationship between diversity. high properties amino acids, carbohydrate, cofactor vitamin metabolisms Taken together, our analyses very relevant perspective out-door air quality, diseases, epidemics, broader implications monitoring.
