The moderately halophilic bacterium Halobacillus halophilus copes with the salinity in its environment by the production of compatible solutes. At intermediate salinities of around 1 M NaCl, cells produce glutamate and glutamine in a chloride-dependent manner (S. H. Saum, J. F. Sydow, P. Palm, F. Pfeiffer, D. Oesterhelt, and V. Müller, J. Bacteriol. 188:6808-6815, 2006). Here, we report that H....

Marine ecosystems are unique and rich reservoirs of biodiversity with high potential toward improving the quality human life. The extreme physical–chemical conditions oceans have favored marine organisms to produce a great variety new molecules as mechanism ensure their survival, such compounds possess biopharmaceutical interest. In particular, microbiota represent promising inexhaustible sourc...
