What Is Geosmin
Geosmin is the aromatic smell of warm earth that may also be found on water and wine. It is this scent of the earth that makes us remember nights of camping in the woods. Geosmin, which refers to the organic volatile compound, produces the sweet odor of fresh earth is found to be produced by a particular enzyme. Geosmin is made up of proteins acted upon by enzymes. Experts discovered geosmin 100 years past. This is specifically produced by the cyanobacteria or blue-green algae in water; while the actinobacteria or Streptomyces are responsible for its production in soil. When the Streptomyces actinobacteria die, the geosmin is emitted as a pungent smell on the earth. The most important use of geosmin is its role in DNA extraction.
Food and Water Spoiler! Geosmin is responsible for the off-tasting water from faucets. When the sample is acidic, geosmin smells benignly. This is why seafood must be soaked in vinegar first to remove the muddy taste.
Geosmin is most pronounced after raining. Geosmin is responsible for most commonly pungent-smelling food like fish, cured meat, beets and other root crops, etc. Geosmin is easily identified by a person’s nose. This in particular, has drawn interest to a lot of wine makers as well water purification experts who want to eliminate the substance out of drinking water as well as in wines; although, a bit of the earthy smell provides a classic note to wines.
Makeup of Geosmin Streptomyces coelicolor is responsible for all the information written about geosmin because the discovery of this organism is what started it all. These are very abundant in soil. Geosmin has two connected parts, which makes all reactions undergo two steps to synthesize geosmin. Geosmin’s two parts are responsible for releasing it and synthesizing the chemical to produce the aromatic scent that it is. These are found out to be related in a metabolic pattern.
Removing the Smell Microbiologists and other experts would really be interested in how geosmin is synthesized and created; as this may help them to discover methods on permanently blocking this from water; which is responsible for its offensive taste. Geosmin is not dangerous to one’s health, although it has the most irritating taste; the impurities in water are the ones that must be eliminated primarily. The elimination of the taste must not mean elimination of geosmin and all its wonderful benefits.
