    摘要: The present invention provides engineered cells and methods for making high purity steviol glycosides, including RebM. In some aspects, the present invention provides host cells, such as bacterial cells (including but not limited to E. coli), that are engineered to overexpress and/or delete or inactivate one or more steviol glycoside transport proteins. The bacterial cells selectively export RebM, or other specific combination of steviol glycosides, out of the cell to increase productivity and reduce production costs associated with downstream purification. Non-target steviol glycosides are not transported to the extracellular medium in significant amounts.
