The engineered E. sp. CGMCC 5087 was inoculated into production medium and incubated at 32°C on a shaker (150 rpm) for 12 h. The culture was centrifuged at 12, 000 rpm for 2 min, and the filtered supernatant was quantified its 2-PE content with GC. Wild type E. sp. CGMCC 5087 was cultured and measured its 2PE content as the control. Wild type E. sp. CGMCC 5087 was cultured in the production medium with 5 g L-1 phenylalanine as another control to verify the effects of phenylalanine.

The yield is 12.5 grams (90%) of phenylacetic acid melting at 76°C

Human perception of flavor involves integration of multiple chemical stimuli from taste and olfactory receptors. Whereas taste receptors respond to a limited set of cues, olfactory receptors respond to thousands of chemicals and provide the diversity of unique food flavors. For example, there are ≈15–20 volatile compounds that, together, constitute the unique flavor of fresh tomatoes (–). These volatiles are derived from various precursors, including fatty acids, carotenoids, and amino acids. Several of the most important tomato aroma volatiles, including 2-phenylacetaldehyde and 2-phenylethanol, are derived from phenylalanine (). The latter, 2-phenylethanol is also a major flavor constituent of such diverse foods as cheese, bread, wine, and olive oil. Both 2-phenylacetaldehyde and 2-phenylethanol have pleasant fruity, floral odors and are major contributors to scent in many flowers, e.g., 2-phenylacetaldehyde in hyacinths and 2-phenylethanol in roses (). Because of its desirable aroma and association with flowers, 2-phenylethanol is the most used fragrance chemical in cosmetic products (). As a consequence, there is much interest in natural sources of 2-phenylethanol for the flavor and fragrance industry.

(R)-(+)-1-PHENYLETHANOL FOR SYNTHESIS | …

Despite the importance of 2-phenylacetaldehyde and 2-phenylethanol to flavor and aroma, it is not clear how plants synthesize them. The yeast Saccharomyces cerevisiae produces 2-phenylethanol from phenylalanine via phenylpyruvate and 2-phenylacetaldehyde (). Deuterium-labeling studies in rose (Rosa damascena Mill.) indicated that there might be as many as four pathways of synthesis (). In addition to the yeast pathway, Watanabe et al. () reported synthesis via a phenethylamine/2-phenylacetaldehyde route and a trans-cinnamic acid/phenyllactate pathway. Because plants contain many aromatic -amino acid decarboxylases (AADCs) (), a pathway that begins with phenylalanine decarboxylation is a reasonable assumption. Here we demonstrate that tomato (Solanum lycopersicum), indeed, uses a pathway whose first step is decarboxylation of phenylalanine to phenethylamine. This reaction is catalyzed by a set of related AADCs. Overexpression of the corresponding genes in transgenic tomato plants led to accumulation of significantly higher levels of 2-phenylacetaldehyde and 2-phenylethanol as well as the related compounds 2-phenylacetonitrile and 1-nitro-2-phenylethane.
