Enterobacteriaceae is present in various niches worldwide (i.e., the gastrointestinal tracts of animals, clinical specimens, and diverse environments) hosts some well-known pathogens salmonellas, shigellas pathogenic coliforms). No investigation has focused on its occurrence marine salterns, it not clear if these hypersaline environments could be a reservoir for bacteria including potentially h...

To investigate the extent of genetic stratification in structured microbial communities, we compared the metagenomes of 10 successive layers of a phylogenetically complex hypersaline mat from Guerrero Negro, Mexico. We found pronounced millimeter-scale genetic gradients that were consistent with the physicochemical profile of the mat. Despite these gradients, all layers displayed near-identical...

Acetohalobium arabaticum Zhilina and Zavarzin 1990 is of special interest because of its physiology and its participation in the anaerobic C(1)-trophic chain in hypersaline environments. This is the first completed genome sequence of the family Halobacteroidaceae and only the second genome sequence in the order Halanaerobiales. The 2,469,596 bp long genome with its 2,353 protein-coding and 90 R...
