Acid creates too harsh of an environment for bacteria and molds to cultivate in. A harsh PH level in either direction will have the same effect. You do, however, need to be careful on using these in consumables. Preservatives are unhealthy to consume (hence the whole organic foods business).

Acid is a preservative because it creates an environment that inhibits the growth of bacteria and other microorganisms that can spoil food. The low pH of acidic conditions can prevent these microbes from thriving, extending the shelf life of the product. Additionally, acid can also enhance the flavor and texture of certain foods, providing a dual function as both a preservative and a flavor enhancer.
