Abstract |
Geosmin, trans-1, 10-dimethyl-trans-9-decalol, is produced by numerous actinomycetes and some blue-green algae. It has been shown to be responsible for earthy/musty odors in public water supplies. Samples of purified geosmin were needed by the U.S. Environmental Protection Agency and by others for use as odor standards and for use in water treatment unit process development studies. This work was carried out to fulfil this need. The microorganism, Streptomyces sp. CWW3, was grown for five days at 28 degrees with shaking in a broth medium. The mixture was steam distilled and the clear distillate extracted with methylene chloride. The geosmin containing methylene chloride extract was separated and the geosmin purified by column and gas chromatography. Seven hundred nine milligrams of geosmin was prepared. |
