Different overexpression strategies for biosynthesis pathway-related enzymes on the production of LNT II. Left: AmpR, ampicillin-resistance gene; SmR, streptomycin-resistance gene; KanR, kanamycin-resistance gene; pBR322, replication origin of pETDuet-1; CloDF13, replication origin of pCDFDuet-1; RSF1030, replication origin of pRSFDuet-1; bent arrows indicate a promoter and T-shaped bars indicate a transcription terminator. Right: the DCW and LNT II of different engineered E. coli strains harboring various plasmids. Error bars indicate standard deviations (n = 3)
