BIOGENERATION OF 2-PHENYLETHANOL AND 2-PHENYLETHYLACETATE IMPORTANT AROMA COMPONENTS

2-Phenylethanol and 2-phenylethylacetate important aroma components ar e obtained in substantial amounts when Hansenula anomala CBS 110 and K loeckera saturnus CBS 5761 are grown with L-phenylalanine as sole nitr ogen source. Up to 2 g/L of mixtures of alcohol and ester are obtained . While in the first microorganism the alcohol predominates, in the se cond the acetate is formed almost exclusively. Experiments with 1-C-13 -D-Glucose show complete incorporation of the label into the methyl gr oup of the acetate.
