Comments Information

    • Unlike HalH6, HalR1 does not appear to be archaeolytic, since it causes no change in the optical density or cell morphology of stationary phase Hbt. salinarum, nor can it form zones of inhibition on fully grown lawns. HalR1 has a dose-dependent, archaeostatic effect on growing Hbt. salinarum.
