This morning I walked out the door and caught a whiff of something I don’t smell often in Los Angeles – actinomycetes!
You know that “rain smell” that you can detect, especially on a day when it hasn’t rained in awhile? That’s actinomycetes. It’s a kind of bacteria that lives in the soil, and when it rains, the water hitting the ground aerosolizes the bacteria, creating that distinctive rain smell. So the next time you catch a whiff of the lovely, fresh scent of rain, don’t forget that it’s actually tiny liquid droplets of dirt bacteria entering your nose. 🙂
