Abstract
Terpenoids are a large family of natural products with remarkable diverse biological functions, and have a wide range of applications as pharmaceuticals, flavors, pigments, and biofuels. Synthetic biology is presenting possibilities for sustainable and efficient production of high value-added terpenoids in engineered microbial cell factories, using Escherichia coli and Saccharomyces cerevisiae which are identified as well-known industrial workhorses. They also provide a promising alternative to produce non-native terpenes on account of available genetic tools in metabolic engineering and genome editing. In this review, we summarize the recent development in terpenoids production by synthetic biology approaches.

The enormous potential of E. coli and S. cerevisiae as platform strains has been confirmed with various successes
Summary
Terpenoids, known as terpenes or isoprenoids, are a large family of natural products. Using IPP/FPP-responsive promoter in E. coli, Shen et al (2016) coordinated the expression of all genes of the MVA pathway from S. cerevisiae using the tunable intergenic regions to increase the availability of FPP.
