FIG. 4.
Impaired growth of Synechocystis strain PCC 6803 lytB(NheI)::Kanr mutant strain on BG-11 agar plates containing 50 μg of kanamycin per ml (upper panel) is much improved by supplementation of the growth medium with 2.5 mM (each) 3-methyl-3-buten-1-ol and 3-methyl-2-buten-1-ol (lower panel). The dark blue-green color of the colonies in the lower panel is comparable to that displayed by the wild type grown on BG-11 agar plates lacking kanamycin and alcohols.
