![]() ![]() They get food but they also distribute the seeds, which benefits the plants.” 11 Our Love Hate Relationship With Geomin 10 Researcher, Mark Buttner, says it’s “analogous to birds eating the fruits of plants. 9 After being drawn in by the smell, bacterial spores stick to springtails, which spread them through their movement and digestion. 8Īdditionally, a new study out of Sweden shows that springtails, tiny arthropods, are attracted to geosmin and another compound called 2-methylisoborneol. 7 Recently, they were able to demonstrate that geosmin deters fruit flies from eating the materials that Streptomyces grows on. Scientists have hypothesized that geosmin may help deter predators and attract organisms that spread bacterial spores. ![]() But, why bacteria produce it was a mystery until recently. We now understand that geosmin is mainly responsible for the earthy smell after rainfall. 5 The bacteria Streptomyces griseus, which is commonly found in soil and freshwater environments, was found to be the source of geosmin. This name comes from two Greek words, ‘geo’ meaning earth, and ‘osme’ meaning odor. ![]() What Causes This Smell?Įlsewhere, in 1966, Gerber and Lechevalier, were conducting research on the smell of soil when they discovered a compound they named geosmin. Plant oils do contribute to that rainy day smell, but they aren’t the primary cause. In a later paper, they hypothesized that the smell was produced by plant oils (stearic acid and palmitic acid) that accumulated in rock and soil during dry periods and were released into the air when rain fell. 3īear and Thomas were getting closer to understanding the earthy smell, but hadn’t yet figured it out. 2 The name change, they argued, would prevent the false assumption that the phenomenon is limited only to clays. The term petrichor originates from two Greek words, ‘petra’ meaning rock, and ‘ikhor’ meaning blood of the gods. They showed that “a wide diversity of rocks and mineral aggregates” could produce the distinct smell and proposed “petrichor” as an alternative term. In 1964, Bear and Thomas, proved otherwise. Mineralogist used to call this rainy day smell “argillaceous odour” because they believed it came from rain mixing with clay and and clay-like components. It also looks at the mixed reactions people have to the scent and why we may find it enjoyable during rainy weather. This article explores the science behind petrichor and the main compound responsible for the smell – geosmin. It’s called petrichor and, it turns out, humans are very sensitive to it. ![]() The familiar aroma fills the air when rain falls after long periods of warm, dry weather.
