Sodium dependence of acetate formation by the acetogenic bacterium Acetobacterium woodii.
Growth of Acetobacterium woodii on fructose was stimulated by Na+; this stimulation was paralleled by a shift of the acetate-fructose ratio from 2.1 to 2.7. Growth on H2-CO2 or on methanol plus CO2 was strictly dependent on the presence of sodium ions in the medium. Acetate formation from formaldehyde plus H2-CO by resting cells required Na+, but from methanol plus H2-CO did not. This is analog...
متن کاملRegulation of caffeate respiration in the acetogenic bacterium Acetobacterium woodii.
The anaerobic acetogenic bacterium Acetobacterium woodii can conserve energy by oxidation of various substrates coupled to either carbonate or caffeate respiration. We used a cell suspension system to study the regulation and kinetics of induction of caffeate respiration. After addition of caffeate to suspensions of fructose-grown cells, there was a lag phase of about 90 min before caffeate red...
متن کاملProduction and Utilization of Ethanol by the Homoacetogen Acetobacterium woodii.
Acetobacterium woodii formed ethanol as a fermentation product in addition to acetate when the phosphate concentration of the medium was between 0.2 and 8.4 mM. Considerable amounts of alanine were also found (2 to 11 mM). Supplementation with phosphate caused a shift to acetate as the only end product. Ethanol could also serve as a substrate for A. woodii. The fermentation yielded predominantl...
متن کاملCarbonic anhydrase in Acetobacterium woodii and other acetogenic bacteria.
Acetobacterium woodii, Acetohalobium arabaticum, Clostridium formicoaceticum, and Sporomusa silvacetica were found to contain carbonic anhydrase (CA). Minimal to no CA activity was detected in Moorella thermoautotrophica, Moorella thermoacetica subsp. "pratumsolum," Sporomusa termitida, and Thermoanaerobacter kivui. Of the acetogens tested, A. woodii had the highest CA specific activity, approx...
متن کاملStoichiometry and deletion analyses of subunits in the heterotrimeric F-ATP synthase c ring from the acetogenic bacterium Acetobacterium woodii.
The ion-translocating c ring of the Na(+) F1 Fo ATP synthase of the anaerobic bacterium Acetobacterium woodii is the first heteromeric c ring found in nature that contains one V- (c1 ) and two F-type-like c subunits (c2 /c3 ), the latter of identical amino acid sequence. To address whether they are of equal or different importance for function, they were deleted in combination or individually. ...
