Abstract
Aerosolized microorganisms may play an important role in climate change disease transmission water and soil contaminants and geographic migration of microbes. While it is known that bioaerosols are generated when bubbles break on the surface of water containing microbes it is largely unclear how viable soil-based microbes are transferred to the atmosphere. Here we report a previously unknown mechanism by which rain disperses soil bacteria into the air. Bubbles tens of micrometres in size formed inside the raindrops disperse micro-droplets containing soil bacteria during raindrop impingement. A single raindrop can transfer 0.01% of bacteria on the soil surface and the bacteria can survive more than one hour after the aerosol generation process. This work further reveals that bacteria transfer by rain is highly dependent on the regional soil profile and climate conditions.
