“…Yarrowia lipolytica has excellent capability of accumulating acetyl-CoA and malonyl-CoA, and is hence a theoretically preferred host for the production of fatty acids, terpenoids, flavonoids, and other compounds that use acetyl/malonyl-CoA as a precursor (Abdel-Mawgoud et al, 2018). In the past few years, the potential of this host has been greatly explored in the biosynthesis of useful compounds such as lipids and biofuels from various carbon sources (Zhu and Jackson, 2015; Du et al, 2016;Ledesma-Amaro et al, 2016;Lv et al, 2019;Ma et al, 2019;Palmer et al, 2020;Shang et al, 2020); however, xylose-based biosynthesis of natural products has been scarcely investigated despite attempts to understand and improve xylose metabolism in Y. lipolytica (Tsigie et al, 2011;Ryu et al, 2015;Rodriguez et al, 2016;Wei et al, 2020b). On one hand, this is attributed to the lower growth rate and biomass accumulation when cells are cultivated in xylose than in glucose (Ledesma-Amaro et al, 2016); on the other hand, the functional and highly efficient expression of heterologous metabolic pathways relevant to natural product biosynthesis depends on sophisticated tools for genetic manipulation, which are still very limited.…”
