Figure 1From: The immediate global responses of Aliivibrio salmonicida to iron limitations Titration of 2,2’-dipyridyl concentration. A. salmonicida strain LFI1238 was grown in LB containing 1% NaCl to an optical density at 0.4 (600 nm). The culture was split into six individual flasks and supplemented with different concentrations of 2,2'-dipyridyl before growth was monitored for 44 hours. Culture treated with 50 μM 2,2'–dipyridyl showed a slight reduction in growth and this concentration was therefore used in all subsequent experiments.Back to article page
