Investigation of the tenacity of airborne microorganisms under real ambient air conditions

How long can bacteria survive in the air? Nobody knows that exactly. Not yet.

Background and Objective

From animal livestock large amounts of bacteria emit into the environment with the exhaust air. The health risks for the residents of the stables are not yet sufficiently clarified, mainly because it is largely unknown how long bacteria in the air are viable.


The aim of this project is to investigate the survivability (tenacity) of microorganisms in the airborne state under real ambient air conditions. For this purpose, a novel bioaerosol chamber is constructed and evaluated, which makes such investigations possible. Afterwards experiments on the tenacity of airborne microorganisms will be carried out in this chamber and the most important influencing factors on their tenacity will be identified. The project thus makes an important contribution to the question of safe distances between animal sheds and neighboring buildings. In the future it will be possible to estimate how long and under which conditions certain microorganisms in the airborne state remain viable and thus potentially infectious.
