A microorganism of the genusPseudomonashas been isolated from the soil by enrichment culture techniques with linalool(I) as the sole source of carbon and energy. The organism is also capable of utilizing limonene, citronellol, and geraniol as substrates but fails to grow on citral, citranellal, and 1,8-cineole. Fermentation of linalool by this bacterium in a mineral salt medium results in the formation of 10-hydroxylinalool(II), 10-carboxylinalool(III), oleuropeic acid(IX), 2-vinyl-2-methyl-5-hydroxyisopropyl-tetrahydrofuran(linalool oxide, V), 2-vinyl-2-methyl-tetrahydrofuran-5-one(unsaturated lactone, VI), and few unidentified minor metabolites. Probable pathways for the biodegradation of linalool are presented.
