According to the American Society for Microbiology, salt is a well-established food preservative, reducing water activity to inhibit microbial growth. However, the effect of salt is not universal and raises a critical question: does salt affect beneficial bacteria differently than harmful ones?. The answer depends heavily on salt concentration and the specific microbial species involved.

For over 8,000 years, ancient civilizations have used sodium chloride, or common table salt, to prevent food spoilage. This time-tested method of food preservation relies on powerful chemical and physical properties to create an environment where harmful microorganisms cannot thrive.

Approximately 6% of the world's total land area is affected by salt, a significant abiotic stress for most living organisms. Understanding what does it mean to be high salt tolerance reveals critical adaptations that allow certain species to survive and prosper where others cannot.
