To date, a small number of aromatics have been produced by recombinant bacteria in laboratory scale while industrial production still requires further strain development. While each study includes some distinct analytical methodology to quantify certain aromatics, a method that can reliably quantify a great number of aromatic products and relevant pathway intermediates is needed to accelerate strain development. In this study, a robust reverse phase high performance liquid chromatography method to quantify a wide range of aromatic metabolites present in host microorganisms using the shikimate pathway, which is the major metabolic pathway for biosynthesis of aromatics is developed. Twenty-three metabolites can be quantified precisely with the optimized method using standard HPLC equipment and UV detection, with the mobile phase used for chromatography also compatible with mass spectrometry (MS). The limit of quantification/ detection is as low as 10⁻¹⁰ to 10⁻¹³ mol, respectively, which makes this method feasible for quantification of intracellular metabolites. This method covers most metabolic routes for aromatics biosynthesis, it is inexpensive, robust, simple, precise and sensitive, and has been demonstrated on cell extracts from 'S. acccharomyces cerevisiae' genetically engineered to overproduce aromatics. | Publication Type: | Journal Article | Source of Publication: | Biotechnology Journal, 12(1), p. 1-7 | Publisher: | Wiley-VCH Verlag GmbH & Co KGaA | Place of Publication: | Germany | ISSN: | 1860-7314 | Fields of Research (FoR) 2008: | 030199 Analytical Chemistry not elsewhere classified | Fields of Research (FoR) 2020: | 340106 Metabolomic chemistry 340101 Analytical spectrometry |
