Where is geosmin found?
Geosmin is a natural bacterial product that is found in beet peels, among other plant parts.
Is Streptomyces good or bad bacteria?
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi.
What produces geosmin?
In the soil, geosmin production is attributed to a single genus of bacteria, called Streptomyces. These are soil-dwelling bacteria which, when faced with unfavourable conditions grow spores (see photo) which can be dispersed to new, more favourable conditions, enabling the bacteria to survive.
Is Geosmin harmful to humans?
Geosmin can be detected by humans at very low levels. Geosmin and MIB produce a musty, earthy smell and taste in drinking water, however both compounds are not harmful at levels present in drinking water.
Is geosmin polar?

How do you treat geosmin?
Conventional treatment processes in water treatment plants, such as coagulation, sedimentation and chlorination have been found to be ineffective for removal of MIB/geosmin. Studies have shown powdered activated carbon, ozonation and biofiltration to be effective in treatment of these two compounds.
Is Streptomyces harmful to humans?

Why are humans good at smelling geosmin?
Though our noses get dismissed as amateurs compared to some animals, there is one compound where we do really well; we can smell geosmin, a chemical (C12H22O) released by dead microbes (commonly Streptomyces bacteria) and which causes that earthy smell, at a level of 5 parts per trillion.
How do I get rid of geosmin smell?
