Biotransformation of Linalool by <i>Botrytis</i> cinerea

Abstract

ABSTRACT Biotransformation of linalool was studied using grape must and three strains of Botrytis cinerea (5901/2; 5909/1; 5899/4). Capillary gas chromatography and combined capillary gas chromatography‐mass spectrometry revealed predominant conversion (&gt;90%) of linalool to (E)‐2,6‐dimethyl‐2,7‐octadiene‐1,6‐diol. in minor concentrations (&lt;10%), the corresponding (Z)‐isomer, 2‐vinyl‐2‐methyl‐tetrahydro‐ furan‐5‐one, the four (E)‐and (Z)‐linalool oxides in their furanoid and pyranoid forms, the (E)‐ and (Z)‐acetates of pyranoid linalool oxides as well as 3,9‐epoxy‐p‐menth‐ 1 ‐ene identified.
