Engineering microbial cell factories for synthesis of glycyrrhetinic acid or other plant natural products. (A) The active components are identified in traditional Chinese herbs or other candidate plants. (B) The fresh samples are collected, and multi-omics technologies are used to discover the biosynthetic pathways of natural products. (C) The Design-Build-Test-Learn cycle is used for construction and optimization of microbial cell factories for natural product biosynthesis. (D) Separation and purification of targeted natural products.
