Assessment of different promoter activities in C. glutamicum ATCC 13032. (A) PBAD activities in C. glutamicum carrying pWYE1067-lacZ exposed to different l-arabinose concentrations. The l-arabinose concentrations are represented by different symbols: 0% (▼), 0.2% (◆), 1% (■), and 2% (●). (B) Promoter activities of Phom, P45, PglyA, Pfda, and Peno in C. glutamicum ATCC 13032. To induce the Ptac promoter, IPTG was added at a final concentration of 1 mM after cultivation for 2 h. (C) The PBAD activities in C. glutamicum carrying pWYE1088-lacZ exposed to different l-arabinose concentrations. The l-arabinose concentrations are represented by different symbols: 0% (▼), 0.02% (▲), 0.2% (◆), 1% (■), and 2% (●).
