    Wording is funky. To clarify:

    The rain smell is due to a compound called geosmin. The bacteria that produces it is Streptomyces.

    When I taught microbiology lab, I would grow a petri dish of Streptomyces during one particular class and have the students smell it

      You mean… You can … Bottle up petrichore ??? How come is there no wide range of perfume/candle/lotion and whatnot?

      Can I make it at home, if so, how would I go about it with everyday items? Can streptomyces cause health issues?

        There’s like an indian family/company that’s been making some hiqh quality petrichor perfume for idk at least 100 years, probably several hundreds, if not a thousand or more idk.

        I forget what it’s called you can probably look it up with perfume pertrichor india

        edit it’s called “Mitti Attar”

          They might’ve been making it for 10,000 years for all I know. I don’t know shit.

          That’s the romanticized, traditional Indian cowshit mix trying to approximate it. (Not doing a disparaging stereotype here, that’s just literally how the article says they make it.)

          I’d be surprised if it actually contains the compound we’re talking about.

            i Kind of doubt it. in a video i saw if the process they were using hardfired bricks. i don’t believe any organic compounds would survive the heat.

            (dung might be a better term for what you were referring to. i seem to remember that because of the way they feed their cattle the dung has a very high fibre content which makes it a good source for building material. it’s nowhere as gross as the diarrhea like consistency we get from cows in Europe)

      Well the smell of rain is actually petrichor, it just has a combination of geosmin and ozone and other chemicals that make that smell.

      Geosmin on its own is just a part of it.
