This study demonstrates the production of value-added compound TAL from glucose using metabolic engineering techniques in an oleaginous yeast. Through the introduction of TAL-producing gene, manipulation of biosynthesis pathways, and optimization of carbon and nitrogen ratios, the production of TAL was significantly improved.
An environmentally sustainable world can be realized by using microorganisms to produce value-added materials from renewable biomass. Triacetic acid lactone (TAL) is a high-value-added compound that is used as a precursor of various organic compounds such as food additives and pharmaceuticals. In this study, we used metabolic engineering to produce TAL from glucose using an oleaginous yeast Yarrowia lipolytica. We first introduced TAL-producing gene 2pyrone synthase into Y. lipolytica, which enabled TAL production. Next, we increased TAL production by engineering acetyl-CoA and malonyl-CoA biosynthesis pathways by redirecting carbon flux to glycolysis. Finally, we optimized the carbon and nitrogen ratios in the medium, culminating in the production of 4078 mg/L TAL. The strategy presented in this study had the potential to improve the titer and yield of polyketide biosynthesis.(c) 2023, The Society for Biotechnology, Japan. All rights reserved.
