title: [PH and oxidation-reduction potential change of environment during a growth of lactic acid bacteria: effects of oxidizers and reducers].
abstract: Decrease of pH and dropping of oxidation-reduction potential have been observed during growing Lactobacillus salivarius 1588 and 3823, Lactobacillus acidophilus 101E, and Lactococcus lactis 3690 in anaerobic conditions in medium with glucose acidification. These parameters and membrane proton permeability of bacteria (C(M)(H+)) changed in the mediums with different pH. Oxidizer ferrycianide and reducer DL-dithiothreitol affected the bacterial growth and their changed H+ extrusion from the cells and K+ uptake by the cells in experiment conditions. Application of oxidizers and reducers are suggested for regulation of growth related with H+ ion transport in lactic acid bacteria.
