Metabolic engineering modification strategy for ectoine production by E. coli and C. glutamicum. a Metabolic engineering modification strategy for ectoine production by E. coli. b Metabolic engineering modification strategy for ectoine production by C. glutamicum. Control element library for transcriptionally balanced expression of the ectoine synthesizes related genes. The library was constructed from 3 BCDs (bicistronic designed elements), 19 promoters and the terminator rrnBT1T2
