Abstract:
Lactic acid fermentation from molasses by L. bulgaricus AU in the presence of caffeine and ammonium fluoride was studied. It was found that caffeine had a stimulating effect only at lower concentration (0.001%-0.002%), while at high concentration the acid-producing activity of the bacteria was considerably depressed. Ammonium fluoride, at a concentration of 0.001%-0.005%, had a stimulating effect on the activity of the bacteria, maximum activity was observed at a concentration of 0.003%.
