The Effect of Fe3O4 Nanoparticles on Survival of Probiotic Bacteria Lactobacillus acidophilus PCM2499 at Lower pH

This paper presents a description of an experiment in which the survival rate of the probiotic bacteria Lactobacillus acidophilus PCM2499 was increased only due to the presence of Fe3O4 magnetic nanoparticles. The survival rate increased from 1.3 to 10 times compare to the control. It has been shown that the minimum concentration of NPs with a positive effect equals 8 mg/ml and the maximum concentration of the NPs equals 24 mg/ml.
