Abstract

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.

摘要

本文介绍了一项实验,在该实验中,仅由于Fe3O4磁性纳米颗粒的存在,益生菌嗜酸乳杆菌PCM2499的存活率得以提高。与对照组相比,存活率提高了1.3至10倍。结果表明,具有积极作用的纳米颗粒的最低浓度为8毫克/毫升,最高浓度为24毫克/毫升。
