Interplay between iron homeostasis and the osmotic stress response in the halophilic bacterium Chromohalobacter salexigens

Nieto Gutiérrez, Joaquín José Argandoña Bertrán, Montserrat Iglesias Guerra, Fernando

In this study, the connection between iron homeostasis and the osmostress response in the halophile Chromohalobacter salexigens was investigated. A decrease in the requirement for both iron and histidine and a lower level of siderophore synthesis were observed at high salinity, and these findings were correlated with a lower protein content in...

The ectD gene, which is involved in the synthesis of the compatible solute hydroxyectoine, is essential for thermoprotection of the halophilic bacterium Chromohalobacter salexigens

Nieto Gutiérrez, Joaquín José García Estepa, Raúl Argandoña Bertrán, Montserrat

The halophilic bacterium Chromohalobacter salexigens synthesizes and accumulates compatible solutes in response to salt and temperature stress. 13C-nuclear magnetic resonance analysis of cells grown in minimal medium at the limiting temperature of 45°C revealed the presence of hydroxyectoine, ectoine, glutamate, trehalose (not present in cells...
