A titration method for the determination of acid and alkali production by micro-organisms

, : A titration method for the determination of acid and alkali production by micro-organisms. Acta Odontol Scand 17(4): 441-465

Suspensions of microorganisms in weak buffers were introduced in a vessel equipped with electrodes, a thermometer, and tubes for introduction of gas, acid and base. The amount of alkali or acid required per unit of time to keep the pH constant was considered a measure of the acid or alkali production activity of the system. Experiments showed a constant production of alkali from urea by staphylococcus albus, and a stimulation of lactate production by lactobacilli in presence of ammonium ions.
