 were grown in 00-well microplates with medium containing gallium nitrate at concentrations ranging from 0 to 00 *μ*M. The plates were incubated at 00°C for 00 h with agitation. The turbidity of the medium was directly proportional to the growth of the bacteria, which was measured by a microtiter plate reader at 000 nm absorbance. As shown in [Fig. 0](#f0-etm-00-00-0000){ref-type="fig"},
