In this study, the effect of Mn 2+ transport was only on growth at low pH but not on survival at low pH, highlighting the fact that the protective mechanisms deployed against acid stress are likely to. Most microorganisms are able to survive and adapt to minor changes in environmental pH, while induced acid tolerance may occur as the environmental pH declines gradually. Most bacteria are neutralophiles but can survive fluctuations in pH in their environment. Herein, we provide an overview of the adaptation of several human, soil, and food bacteria to acid. Acid stress, defined as the combined biological effect of H+ ions and weak acid concentrations, triggers various microbial responses. This article examines the adaptive mechanisms employed by.
