They were the representatives of the Swedish University of Agricultural Sciences, the John Innes Center and Lund University, who decided to explain its origin. Distinctive scentthat we feel in the spring.

As it turns out, all the confusion stems from the presence of geosmin, a compound found in soil and the result of a symbiotic relationship between bacteria of the genus streptomycesAnd the so-called spring. As the researchers note, these animals are attracted to the odors emitted by the aforementioned colonies of bacteria.
Before scientists make such observations, they put forward a hypothesis according to it streptomyces They must have some benefit from geosmin production. And this is the case. This was confirmed by a simple experiment in which two groups were placed together with some kind of magic. The first contained the tested bacteria, while the second contained control agents. It soon became apparent that the springtail definitely prefers the first option.
The scent of spring is associated with the presence of geosmin, which is produced by bacteria of the genus streptomyces
To ensure that it is actually about connecting relationships streptomyces With these arthropods, the researchers conducted two more experiments. The results were similar, so it turns out that there is a connection between bacteria and these animals. The blobtail appears to be attracted not only to geosmin, but also to another compound known as 2-MIB.
Both of these substances act as chemical signals to attract springtails. But what’s all the fuss about? These arthropods feed on bacteria of the genus streptomyces. Interestingly, many other species, including the famous fruit flies, die from contact with substances produced by these bacteria. Springtails, however, are immune to them, having diverged from insects about half a billion years ago. In the course of evolution, they have developed enzymes that provide protection against the chemical arsenal of described microorganisms.

This gives the pulsating tail access to the food while the bacteria use the other side to distribute the spores. The latter may attach themselves to the bodies of springtails, and then fall off in different places, increasing their range of occurrence. There is another type that assumes the excretion of these germs with feces.
In summary: when bacteria of the genus streptomyces In an effort to encourage springtails to come along, they have begun producing geosmin. Our noses are very sensitive to the smell of this substance. It is especially common during the spring rains. As you can see, even such daily fluctuations may require a scientific explanation. So the next time you smell spring, remember that somewhere in the surrounding soil is a symbiotic relationship between bacteria and arthropods.
Echo Richards embodies a personality that is a delightful contradiction: a humble musicaholic who never brags about her expansive knowledge of both classic and contemporary tunes. Infuriatingly modest, one would never know from a mere conversation how deeply entrenched she is in the world of music. This passion seamlessly translates into her problem-solving skills, with Echo often drawing inspiration from melodies and rhythms. A voracious reader, she dives deep into literature, using stories to influence her own hardcore writing. Her spirited advocacy for alcohol isn’t about mere indulgence, but about celebrating life’s poignant moments.
