How does salt affect bacteria
WebSome bacteria prefer salty environments and are thus called halophiles. Extreme halophiles, such as Halobacterium, show optimum growth in conditions of 20 to 30 percent salt and will lyse (break open) if this salt level is reduced. Such bacteria are found in the Dead Sea, in brine ponds, and occasionally on salted fishes and hides.
