The invention discloses
bifidobacterium animalis subsp. Lactis, a preparation and application of the
bifidobacterium animalis subsp. Lactis in regulation of depression and intestinal
flora. Belongs to the technical field of
probiotic preparation. According to the application, seven strains of
bacteria are separated from excrement of infants, the seven strains of
bacteria comprise
bifidobacterium breve,
bifidobacterium animalis and
bifidobacterium longum through identification, the anti-depression capacity of the seven strains of
bacteria is evaluated through in-vitro experiments, a potential
antidepressant bifidobacterium animalis subsp. Lactis BD1 is screened out, and further experiments prove that the
antidepressant bifidobacterium animalis subsp. Lactis BD1 has the advantages that the
antidepressant bifidobacterium animalis subsp. Lactis BD1 can be used for preparing the antidepressant bifidobacterium animalis subsp. Lactis BD1; the strain has the effects of improving depressive
mood,
intestinal bacteria unbalance and insufficient
serotonin secretion in the brain caused by chronic bound stress (CRS), and compared with bifidobacterium animalis subsp. Lactis in the prior art, the strain achieves the anti-depression effect from multiple aspects, also has the effect of adjusting intestinal
flora imbalance, and has the advantages of being safe and reliable. And a new
treatment strategy is provided for depression and intestinal
flora imbalance.
