Sensitivity and resistance to CO
shown by comparing colony forming units (CFUs). Each strain was grown overnight in LB broth and diluted 106 fold, and then 100 μl was spread on each plate and incubated. Upper panel: wild type Salmonella (14028) on LB media in air (left) or 5% CO2 (right). Lower panel; YS1646 on LB media in air (left) or 5% CO2 (right).
