FIG. 2.

Effects of disruption of qsuD on the growth of C. glutamicum cells. The C. glutamicum R wild-type strain containing the control vector plasmid pCRB1 (A) and the qsuD-deficient strain containing pCRB1 (B) or a plasmid carrying the tac promoter-qsuD construct (C) were grown in BT minimal medium supplemented with either glucose (black squares), quinate (white circles), or shikimate (white triangles). The optical density at 610 nm (OD₆₁₀) was monitored. Similar results were obtained from two independent experiments, and representative results are shown.
