Abstract
How Light Exposure Changes Bacterial Communities in Household Dust

BUILT ENVIRONMENT The collection of buildings, roads, cities, and even parks are the habitat that we have built for ourselves
A research team at the Biology and the Built Environment Center wanted to perform an experiment to discover how bacteria living in dust would be a ected when they were exposed to light [ ]
By comparing the dust sample treated with propidium monoazide (PMA) to the untreated sample, we could compare the DNA that we found in the dust and figure out which types of bacteria died when exposed to light
Summary
Biology and the Built Environment Center, University of Oregon, Eugene, OR, United States. AGE: BUILT ENVIRONMENT The collection of buildings, roads, cities, and even parks are the habitat that we have built for ourselves. Did you know that there are bacteria living in the dust found inside many buildings? Most of these bacteria are harmless, but some might make us sick. We wanted to test how bacteria living in dust would be a ected by light: which types would live and which types would die? We put dust in model o ces for days, under di erent lighting conditions, and measured the e ects of light on the bacteria in that dust. Understanding how di erent kinds of microbes thrive or decline in di erent environments is crucial, as we strive to create buildings of the future that can help us stay healthy, or at least do not make us sick as often
