Birk, Florian published the artcileAroma active alkylated pyrazines are produced by Basfia succiniciproducens as by-products of succinic acid production, Synthetic Route of 14667-55-1, the main research area is Basfia succinic acid flavor dynamic headspace extraction.
Culture supernatants of Basfia succiniciproducens derived from the industrial production of succinic acid exhibit an intense nutty, root vegetable-like, buttery and sourish smell. By means of headspace-gas chromatog.-mass spectrometry-olfactometry (HS-GC-MS-O), 14 odor-active compounds were perceived and identified using two GC-columns of different polarity and comparison of retention indexes and mass spectra to those of authentic reference compounds Several alkylated pyrazines, including 2,3,5-trimethylpyrazine, 5-ethyl-2,3-dimethylpyrazine, 2,3,5,6-tetramethylpyrazine, 2,3,5-trimethyl-6-ethylpyrazine, 2,3,5-trimethyl-6-propylpyrazine and 2,3,5-trimethyl-6-butylpyrazine were found to contribute to the aroma of the culture supernatant. Quantitation of the pyrazines was performed by means of dynamic headspace-GC-MS after standard addition, and 2,3,5,6-tetramethylpyrazine (9.10 mg/L) was the most abundant compound Waste streams of the biotechnol. production of commodity chems. may thus represent a sustainable resource for the isolation of aroma compounds
