Figure 6.
Fluorescence microscopy of UV exposed (50 J/m2) cells carrying the cloning vector pKK232-8 or plasmid pBK410 (tisAB overexpression) followed by growth for 1 and 2.5 h. Cells were grown in K-medium and stained with acridine orange. (A) AB1157/pKK232-8, unexposed; (B) AB1157/pKK232-8, 1 h after UV; (C) AB1157/pKK232-8, 2.5 h after UV; (D) AB1157/pBK410, unexposed; (E) AB1157/pBK410, 1 h after UV; (F) AB1157/pBK410, 2.5 h after UV.
