Adaptive laboratory evolution (ALE) plays a crucial role in microbial breeding by simulating natural evolution process and rapidly obtaining strains with stable traits. It provides a powerful tool for constructing stable microbial cell factories and has been widely used in improving target product synthesis, expanding substrate utilization range, and enhancing chassis cells' tolerance. ALE also employs stress strategies to enhance the production of target compounds.
Due to the complexity of metabolic and regulatory networks in microorganisms, it is difficult to obtain robust phenotypes through artificial rational design and genetic perturbation. Adaptive laboratory evolution (ALE) engineering plays an important role in the construction of stable microbial cell factories by simulating the natural evolution process and rapidly obtaining strains with stable traits through screening. This review summarizes the application of ALE technology in microbial breeding, describes the commonly used methods for ALE, and highlights the important applications of ALE technology in the production of lipids and terpenoids in yeast and microalgae. Overall, ALE technology provides a powerful tool for the construction of microbial cell factories, and it has been widely used in improving the level of target product synthesis, expanding the range of substrate utilization, and enhancing the tolerance of chassis cells. In addition, in order to improve the production of target compounds, ALE also employs environmental or nutritional stress strategies corresponding to the characteristics of different terpenoids, lipids, and strains.
