Fig. 2From: Comparison of five bacterial strains producing siderophores with ability to chelate iron under alkaline conditionsGrowth of the bacteria studied. The bacteria, in exponential phase of growth, were inoculated in minimal medium (MM) broth (except A. vinelandii, which was inoculated in Burk´s medium broth), iron-deficient, and incubated at 30 °C with agitation (150 rpm). This is a typical example of an experiment performed at least two times. Each point represents the average of three determinationsBack to article page
