X49 is a member of the family within the order and can be isolated from salt-fermented larval gizzard shad. The genome of X49 reported here provides a genetic basis for its halophilic character. Diverse genes were involved in salt-in and -out strategies enabling adaptation of X49 to hypersaline environments. Due to resistance to high salt concentrations, genome research of X49 will contribute to the improvement of environmental and biotechnological usage by enhancing understanding of the osmotic equilibrium in the cytoplasm. Its genome consists of 3,584,631 bp, with an average G + C content of 59.1%, and 3261 coding sequences, 12 rRNAs, 66 tRNAs, and 8 miscRNAs.

The application of low-salt fish sauce is limited by its tendency to spoil easily and inadequate flavor generation. Herein, a salt-tolerant Tetragenococcus halophilus 2MH-3 strain with strong abilities of enzyme production and biogenic amine degradation was utilized as a starter for the production of low-salt fish sauce. Bacterial community analysis revealed discrepancies in microbiota between low-salt fish sauces fermented with (Th group) or without 2MH-3 (LF group).

Five halophilic archaeal strains, XH8T, CK5-1T, GDY1T, HW8-1T, and XH21T, were isolated from commercial coarse salt produced in different regions of China. Their 16S rRNA and rpoB' gene sequences indicated that four of the strains (CK5-1T, GDY1T, HW8-1T, and XH21T) represent distinct species within the genus Haloplanus (family Haloferacaceae), while strain XH8T represents a novel genus within the same family. These assignments were supported by phylogenetic and phylogenomic analyses, which showed that strains CK5-1T, GDY1T, HW8-1T, and XH21T cluster with the current species of the genus Haloplanus, while strain XH8T forms a separate branch from the genus Haloplanus.

Halocins, the proteinaceous antimicrobial agents produced by haloarchaea, may be used for the preservation of salted foods and the treatment of diseases. For their application and function explanation, it is necessary to produce the active recombinants. In this work, a haloarchaeal strain producing halocin was isolated from the salt-fermented shrimp and identified as Natrinema sp.
