Growth-Coupled Carotenoids Production Using Adaptive Laboratory Evolution

Adaptive laboratory evolution is a powerful technique for strain development. However, the target phenotypes using this strategy have been limited by the required coupling of the phenotype-of-interest with fitness or survival, and thus adaptive evolution is generally not used to improve productProduct formation. If the desired productProduct confers a benefit to the host, then adaptive evolution can be an effective approach to improve host productivity. In this book chapter, we describe an effective adaptive laboratory evolution strategy for improving productProduct formation of carotenoids, a class of compounds with antioxidantAntioxidant potential, in the yeast Saccharomyces cerevisiae.
