RodZ and PgsA Play Intertwined Roles in Membrane Homeostasis of and Resistance to Weak Organic Acid Stress.

Weak organic acids like sorbic and acetic acid are widely used to prevent growth of spoilage organisms such as Bacilli. To identify genes involved in weak acid stress tolerance we screened a transposon mutant library of for sorbic acid sensitivity. Mutants of the () gene were found to be hypersensitive to the lipophilic weak organic acid.

All Three Endogenous Quinone Species of Escherichia coli Are Involved in Controlling the Activity of the Aerobic/Anaerobic Response Regulator ArcA.

The enteron Escherichia coli is equipped with a branched electron transfer chain that mediates chemiosmotic electron transfer, that drives ATP synthesis. The components of this electron transfer chain couple the oxidation of available electron donors from cellular metabolism (e.g.

Intracellular pH Response to Weak Acid Stress in Individual Vegetative Bacillus subtilis Cells.

Unlabelled: Intracellular pH (pH) critically affects bacterial cell physiology. Hence, a variety of food preservation strategies are aimed at perturbing pH homeostasis. Unfortunately, accurate pH quantification with existing methods is suboptimal, since measurements are averages across populations of cells, not taking into account interindividual heterogeneity.
