How can I obtain cheap geosmin-scented air freshener? Answered
What's the cheapest (safe and legal) way to obtain a small quantity of relatively pure geosmin? By "small" I mean an amount sufficient to keep a room smelling like rich earth for weeks. By "relatively pure" I mean it won't turn funky or give someone a nasty case of fungal pneumonia. Brew it? I know dehydration and alkali could -help- isolate Streptomyces, but then what? I don't have access to ready-made selective media nor money to buy strange supplies.
