Bacteria represent an important part of the microbial abundance and diversity in a wide va Airborne bacteria riety of rural and urban outdoor bioaerosols. Currently, airborne bacterial communities are mainly sampled in Atmosphere two aerosol size fractions (2.5 and 10 µm) and characterized by culture-dependent (plate-counting) and culture- Bacterial communities independent (DNA sequencing) approaches.
