Demonstrates the individual roles of acid resistance systems in E. coli fermentation, suggesting critical functions in pH control.
. Thus, our data show that each AR system possesses a crucial and distinct role in Δp formation that is highly dependent on the acid stress level. Moreover, the role of one AR system was, in most cases, not fully compensated by the others, underscoring the importance of these AR systems individually in pH homeostasis in E. coli during fermentation.
