The invention discloses a
Lactobacillus fermentum strain Zhao which can regulate
intestinal motility and prevent
constipation. The preservation number is CCTCC NO: M 2013513 and its application. After 3 hours in gastric juice, the
survival rate reached 85.12±5.18%. It can grow slowly under 1.0% concentration of bile salt, and the growth efficiency reaches 18.33±0.52 of culture without bile salt. The hydrophobicity of
Lactobacillus fermentum strain Zhao cells also reached 70.80±0.61 %. Can grow normally in the
human intestine. Experiments in mice also showed that
Lactobacillus fermentum strain Zhao can slow down the
weight loss trend of mice caused by
constipation, accelerate the time of black stool
discharge, improve the propulsion rate of the
small intestine, and increase serum MTL, Gas, ET, The levels of AchE, SP and VIP factors, decreased SS factors, increased
food intake and
water intake, decreased
defecation volume, the number of defecated particles and the trend of decreasing
water content in
feces, played a similar role to
constipation drugs, showing a certain preventive effect on constipation .
