Expression of mgtA encoding a magnesium transporter is activated in the absence of the main Mg2+ transporter CorA in Salmonella
<p><i>Salmonella</i> imports magnesium via three known transporters, the widely conserved CorA transporter and the MgtA and MgtB P-type ATPases. CorA is expressed under various growth conditions whereas the other two magnesium transporters, MgtA and MgtB, are expressed under conditions of magnesium starvation under the positive control of the PhoP-PhoQ regulatory system. <br>Our recent results suggest that production of MgtA, but not that of MgtB, is activated in the absence of the main Mg2+ transporter CorA (Metaane <i>et al </i>2022, 2023 ) <br>This hypothesis was further validated in this study by using transcriptional and translational <i>lacZ </i>fusions in the <i>mgtA </i>and <i>mgtB</i> genes. In addition, our data suggest that regulation of expression of MgtA in the absence of CorA is post-transcriptional . </p><p><strong>This work was supported by the French National Research Agency (ANR-19-CE44-0005-01, PERIOMET project).</strong> </p><p>Metaane S, Monteil V, Ayrault S, Bordier L, Levi-Meyreuis C, Norel F.

Data from: Mechanism of Ca2+, Mg2+ and Fe3+ in fine cassiterite flotation using octanohydroxamic acid
The existence of metal ion should not be ignored in both hydrometallurgy and flotation. In this study, the effects of Ca2+, Mg2+ and Fe3+ on the flotation performance of cassiterite using octanohydroxamic acid (OHA) as the collector were investigated by the micro-flotation tests, X-ray photoelectron spectroscopy (XPS), fourier transform infrared spectroscopy (FTIR), contact angle, zeta (ζ) potential measurements and atomic force microscopy (AFM) imaging. The results of the flotation and contact angle experiments showed that the addition of Ca2+, Mg2+ and Fe3+ significantly decreased both the recovery and contact angle of cassiterite within pH ranged from 6.0 to 12.0 in the presence of OHA collector. ζ–potential measurements, solution chemistry analysis and FTIR measurements indicated that the flotation recovery of the cassiterite declined due to the CaOH+, MgOH+ and Fe(OH)3 sites on the cassiterite surface. XPS results indicated that the chemisorption of OHA on cassiterite surface and its adsorption combined with calcium ions effects finally changed the chemical properties of cassiterite surface. The AFM images also revealed that new species Fe(OH)3 of Fe3+ formed and adsorbed on the cassiterite surface at pH of 9.0. The adsorption of Fe(OH)3 reduced the adsorption of OHA on the cassiterite surface, thus the hydrophobicity of cassiterite was deteriorated.
