Such activity is specific towards certain bacteria only, as the development of beneficial bacteria, such as lactobacilli spp. is improved under these conditions. Protons (liberated during dissociation of organic acids) and anions may serve as a pH barrier against pathogen colonization at the brush border. , 2006). An alternative hypothesis for the mode of action of organic acids has been proposed by Russell (1992), who attributed the toxic effects of organic acids to an accumulation of polar anions in the cell wall, which is dependent on the pH gradient across the membrane of the bacterial cell.

Thus, anti-bacterial activities of organic acids are influenced by the pH of the intestinal tract. The higher the pH value, the more they will tend to dissociate. Efficacy of different acidifiers against salmonella in animal production A row-dilution-test (Sadler and Binder, 1996) was carried out in order to determine the anti-bacterial effect of different test substances (organic acids) against salmonella, following the same design as described in chapter “Possibilities of E. coli control by using acidifier in livestock production” (see page 17).
