Pseudomonas carveol

As mentioned before, a Pseudomonas incognita was isolated by enrichment technique on the monoterpene alcohol linalool that was also able to grow on geraniol, nerol and limonene [36]. The metabolism of limonene by this bacterium was also investigated [37]. After fermentation the medium yielded as main product a crystallic acid, perillic acid, together with unmetabolised limonene, and some oxygenated compounds dihydrocarvone, carvone, carveol, p-menth-8-en-1 -ol-2-one, p-menth-8-ene-1,2-diol or p-menth-1 -ene-6,9-diol (structure not fully elucidated) and finally / -isopropenyl pimelic acid. 

Pseudomonas PX 1 biotransformed (+)-a-pinene (4) to give (+)-cA-thujone (29) and +)-trans-carveol (81a) as major compounds. Compounds 81a, 171, 173, and 178 have been identi ed as fermentation products (Gibbon and Pirt, 1971 Gibbon et al., 1972) (Figure 19.150).
