Abstract

Of 104 yeasts tested for the hydrolysis of rac-linalyl acetate and rac-α-terpinyl acetate twelve hydrolysed rac-linalyl acetate. Five of these belonged to five different species of Geotrichum. The most promising strain, Geotrichum capitatum CBS 0572.82, yielded (S)-linalool in 56% enantiomeric excess after 6h (E value ∼5, c = 32%). Only one unclassified yeast isolate hydrolyzed rac-α-terpinyl acetate with a slight preference for the S-enantiomer (E value ∼2).
