    • Function

    • Antibacterial activity against the haloarchaeons H.salinarium NRC817, Halobacterium GRB and H.gibbonsii.
    • Miscellaneous

    • Halocin-S8 is quite robust, as it can be desalted, boiled, subjected to organic solvents, and stored at 4 degrees Celsius for extended periods without losing activity.
