Structural Characteristics and Functional Implications of PM_2.5 Bacterial Communities During Fall in Beijing and Shanghai, China.

ABSTRACT: Air pollution characterized by fine particulate matter (PM_2.5) frequently has occurred in China, and has posed threats to human health. The physiochemical characteristics of airborne PM_2.5 have been extensively studied, but its bacterial structures and functions have not yet been well studied. Herein, we focused on the structural characteristics and functional implications of airborne bacteria under different pollution levels in Beijing and Shanghai. The α- and β-diversities showed no obvious difference in two cities (p > 0.05). The dominant phyla Proteobacteria, Firmicutes, and Actinobacteria with total abundance of over 92% were found in all PM_2.5 samples. The results of weighted unifrac non-metric multidimensional scaling (NMDS) suggested that air
