The intracellular pH was measured in growing Acetobacterium wieringae and Acetobacter aceti with an acid equilibrium distribution method. [14C]-acetylsalicylic acid, [14C-benzoic acid and [14C]-acetic acid were used as ΔpH-indicators. The extracellular pH of Acetobacterium wieringae decreased from 7.0 to 5.0 during growth; accordingly, the intracellular pH changed from 7.1 to 5.5, and a ΔpH between 0.1 and 0.65 (interior more alkaline) was maintained. Corresponding results were obtained for… 
Production of acetic acid by Acetogenium kivui
TLDR
Enzymatic studies indicate that in A. kivui pyruvate ferredoxin-oxidoreductase and acetate kinase are inhibited at acetate concentrations higher than 800 mM, which allowed this bacterium to produce more than 700 mM acetic acid within 40–50 h.
The internal pH of Clostridium acetobutylicum and its effect on the shift from acid to solvent formation
TLDR
The internal pH stayed above 5.5 in cultures that shifted from acid to solvent formation, a prerequisite for the shift, and the possible function of high internal concentrations of butyrate, butyryl phosphate and butyr coenzyme A in the triggering mechanisms of the shift is discussed.
Alanine racemase from the acidophile Acetobacter aceti.
Reaction engineering analysis of hydrogenotrophic production of acetic acid by Acetobacterium woodii.
TLDR
In order to establish a process for the hydrogenotrophic production of acetic acid, the formation of acetate by Acetobacterium woodii was studied in a batch-operated stirred-tank bioreactor at different hydrogen partial pressures (pH₂) in the gas phase.
Carrier-mediated acetate transport in Acetobacterium woodii
TLDR
Both, growing and resting cells of A. woodii showed no equilibrium between internal and external acetate concentrations during glucose consumption; the internal concentrations were always higher than expected assuming equal concentrations of the free acid inside and outside the cells.
Correlation between acetic acid resistance and characteristics of PQQ-dependent ADH in acetic acid bacteria
TLDR
Results suggest that high ADH activity in the Ga. europaeus cells and high acetic acid stability of the purified enzyme represent two of the unique features that enable this species to grow and stay metabolically active at extremely high concentrations of acetic Acid.
Functional analysis of the acetic acid resistance (aar) gene cluster in Acetobacter aceti strain 1023
TLDR
The primary role of the aar genes in the metabolically streamlined industrial strain A. aceti 1023 appears to be to harvest energy via acetate overoxidation in otherwise depleted medium.
Acidophilic adaptations in the structure of Acetobacter aceti N5-carboxyaminoimidazole ribonucleotide mutase (PurE).
TLDR
Increased inter-subunit hydrogen bonding and an increased number of arginine-containing salt bridges appear to account for the bulk of the increased acid stability of Acetobacter aceti PurE.
Long‐term continuous evolution of acetate resistant Acetobacter aceti
TLDR
Intracellular acetate concentrations were significantly lower in evolved A. aceti and E. coli, indicating that cytoplasmatic anion accumulation is an important component of acetate toxicity.

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.
The internal pH of Clostridium acetobutylicum and its effect on the shift from acid to solvent formation
TLDR
The internal pH stayed above 5.5 in cultures that shifted from acid to solvent formation, a prerequisite for the shift, and the possible function of high internal concentrations of butyrate, butyryl phosphate and butyr coenzyme A in the triggering mechanisms of the shift is discussed.
THE NUTRITIONAL REQUIREMENTS OF ACETOBACTER MELANOGENUM AND RELATED SPECIES
During the course of some physiological studies with Acetobacter melanogenum it became necessary to investigate the nutritional requirements of several isolates in considerable detail. Grey and Tatum
Purification and Characterization of Aldehyde Dehydrogenase of Acetobacter aceti
TLDR
The purification and characterization of the enzyme of A. aceti IFO 3284 are described and compared with the enzyme from G. suboxydans, and two genera of acetic acid bacteria are compared to each other.
The internal-alkaline pH gradient, sensitive to uncoupler and ATPase inhibitor, in growing Clostridium pasteurianum.
TLDR
The results suggest that the pH gradient is formed by an ATPase-driven extrusion of protons from the cells rather than by a Donnan potential.
The transmembrane electrical potential and intracellular pH in methanogenic bacteria.
TLDR
The magnitudes of the electrical potential and proton gradient in Methanospirillum hungatei GP1 and Methanobacterium thermoautotrophicum were determined and are interpreted in terms of proton efflux and monovalent cation antiport activities at the cytoplasmic membrane, with possible proton pumping at the site of internal vesicles.
Electrochemical proton gradient and lactate concentration gradient in Streptococcus cremoris cells grown in batch culture
TLDR
The results supply strong experimental evidence for the energy recycling model postulated by Michels et al., and imply that especially at high pH values the carrier-mediated efflux of lactate supplies a significant quantity of metabolic energy to S. cremoris cells.
VIOLOGEN DYE INHIBITION OF METHANE FORMATION BY METHANOBACILLUS OMELIANSKII
TLDR
Low concentrations of methyl or benzyl viologen inhibit the formation of CH(4) from ethanol and CO(2) by washed cells of Methanobacillus omelianskii, and Hydrogen, which is normally formed from ethanol, accumulates in greater quantities when CH( 4) formation is inhibited by viologens.
The proton electrochemical gradient in Escherichia coli cells.
TLDR
A similar pattern of dependence of delta pH on extracellular pH was observed in EDTA/valinomycin-treated cells but the delta psi was almost constant over the whole range of extrace cellular pH values (6-8) implying electroneutral proton movement.
