In this study, we determined the internal cellular pH response of Leuconostoc mesenteroides and Lactobacillus plantarum to the external pH created by the microorganisms themselves or by lactic or acetic acids and their salts added to the growth medium. Growth of Leuconostoc mesenteroides stopped when its internal pH reached 5.4 to 5.7, and growth of L. plantarum stopped when its internal pH reached 4.6 to 4.8. Variation in growth medium composition or pH did not alter the growth-limiting… 
Induction of the acid tolerance response in Leuconostoc mesenteroides ATCC 8293 by pre-adaptation in acidic condition
TLDR
The effect of preadaptation of L. mesenteroides under mildly acidic conditions for resistance to normally lethal levels of acid stress is investigated and shows maximum increase in tolerance.
pH Homeostasis and Citric Acid Utilization: Differences Between Leuconostoc mesenteroides and Lactococcus lactis
TLDR
It could be concluded that citric acid allows the maintenance of pH homeostasis in Leuconostoc mesenteroides.
Effect of Lactobacillus plantarum and Leuconostoc mesenteroides starter cultures in lower salt concentration fermentation on the sauerkraut quality
This research was aimed to study the effect of Lactobacillus plantarum and Leuconostoc mesenteroides starter cultures application in lower salt concentration fermentation on sauerkraut quality. Fresh
Effect of process parameters on the production and drying of Leuconostoc mesenteroides cultures
TLDR
Viable counts were not affected by scaling the volume of the fermentation from 2 to 15 l, or by the type of centrifuge used to concentrate the cells, but freeze-dried powders obtained from the continuous pilot-plant-centrifuged cultures had, on the average, 33% lower populations than those obtained from a laboratory unit.
The acid-stress response in Lactobacillus sanfranciscensis CB1.
TLDR
Two-dimensional gel electrophoresis analysis of protein expression by non-adapted, acid- adapteded and acid-tolerant mutant cells of LB: sanfranciscensis showed changes in the levels of 63 proteins, including the highest induction factor of those proteins specifically induced in the acid- Adapted cells.
Population Heterogeneity of Lactobacillus plantarum WCFS1 Microcolonies in Response to and Recovery from Acid Stress
TLDR
The heterogeneity of the population, calculated from the microcolony areas, decreased with recovery from pH 3 over a period of a few hours, and specific regions within single filamentous cells were more able to form rapidly dividing cells, i.e., there was heterogeneity even within single recovering cells.
Elucidation of the mechanism of lactic acid growth inhibition and production in batch cultures of Lactobacillus rhamnosus
TLDR
The results obtained confirmed that the specific growth rate reached zero at approximately the same lactate concentration for all the pH values studied, showing that generalisations made from studies performed within very narrow ranges of pH are not valid and that the non-dissociated form of lactic acid is not the only inhibiting species.
ISOLATION AND IDENTIFICATION OF ALOCALSTRAIN OF PROBIOTIC BACTERIAL ACTOBACILLUS PLANTARUM AND STUDIED THE TOLERANCE ABILITY FOR DIFFERENT LEVELS OF pH
TLDR
Lactobacillus plantarum IRQ12 was isolated from local pickle producing from Cucumis sativus submerged in 5% salt solution for one week far from sun light and strain tolerance ability was investigated for different levels of pH 4.
Unravelling the multiple effects of lactic acid stress on Lactobacillus plantarum by transcription profiling.
The organic acid lactate is the predominant fermentation product of Lactobacillus plantarum. The undissociated form of this organic acid is a strong growth inhibitor for the organism. Different

Membrane ATPases and acid tolerance of Actinomyces viscosus and Lactobacillus casei
TLDR
Lactobacillus casei ATCC 4646 and Actinomyces viscosus OMZ105E were found to differ markedly in acid tolerance, and the major differences pertinent to the physiology of the organisms appeared to be related to proton-translocating ATPases.
Uncoupling by Acetic Acid Limits Growth of and Acetogenesis by Clostridium thermoaceticum
TLDR
It seems unlikely that mutations at one or a few loci would result in C. thermoaceticum cells significantly more acetic acid tolerant than their parental type, as these cells require an internal pH of at least 5.5 to 5.7.
Bioenergetics of lactic acid bacteria: cytoplasmic pH and osmotolerance
TLDR
A specific strain of Lactobacillus acidophilus has been found to be unusually osmotolerant, which is due to the cells' capacity to accumulate glycine betaine by a transport carrier that is activated, but not induced, by high medium osmotic pressure.
Influence of External pH and Fermentation Products on Clostridium acetobutylicum Intracellular pH and Cellular Distribution of Fermentation Products
TLDR
The data demonstrate that acetate and butyrate are concentrated within the cell under acidic conditions and thus tend to lower the intracellular pH, thereby circumventing a decrease in the intrACEllular pH great enough to be deleterious to the cell.
Physiological adaptations of anaerobic bacteria to low pH: metabolic control of proton motive force in Sarcina ventriculi
TLDR
The results indicate that S. ventriculi is an acidophile that can continue to produce ethanol at low cytoplasmic pH values and both the ability to shift to ethanol production and the ability of the organism to continue to ferment glucose while cytopanal pH values are low adapt S. Ventriculi for growth at low pH.
Dissipation of the proton motive force in oral streptococci by fluoride
TLDR
P pH equilibration in media of low pH would lead to a greater reduction of metabolic activity than when it occurs in media at neutral pH, and the growth of streptococci, with or without added F-, is limited when the intracellular pH falls below about 5.7.

A Differential Medium for the Enumeration of Homofermentative and Heterofermentative Lactic Acid Bacteria
TLDR
A medium was developed for the differential enumeration of homofermentative and heteroferMENTative lactic acid bacteria and a total of 21 Lactobacillus, Pediococcus, Leuconostoc, and Streptococcus species were correctly classified with the medium.
A proton-translocating ATPase regulates pH of the bacterial cytoplasm.
TLDR
It is suggested that cytoplasmic alkalization is diminished when alkaline pH of the cy toplasm is over 7.7, because of a low activity of proton extrusion by the H+-ATPase, and consequently, the cytop lasmic pH is regulated at about7.7.
