The invention discloses Lactobacillus fermentum zhao capable of regulating intestinal movement and preventing constipation and application thereof, wherein the preservation number of the Lactobacillus fermentum zhao is CCTCCM2013513. The strain has higher acid resistance, has a survival rate reaching 85.12% plus/minus 5.18% after staying in pH3.0 artificial gastric juice for 3 h, can grow slowly in cholate with the concentration of 1.0% and has a growth efficiency reaching 18.33% plus/minus 0.52% of that of cholate-free culture. The hydrophobicity of Lactobacillus fermentum zhao cells is up to 70.80% plus/minus 0.61%. The Lactobacillus fermentum zhao can grow normally in human intestinal tracts. In-vivo tests using mice show that the Lactobacillus fermentum zhao can reduce the weight reduction tendency of the mice, shorten the time of defecation of dark stool, improve the peristalsis of small intestines, increase MTL, Gas, ET, AchE, SP and VIP factors to different extents, reduce SS factors, increase food consumption and water consumption, reduce the tendency that stool amount, stool pieces and stool water content decline, play an effect similar to that of a constipation medicine and show a certain constipation prevention effect.
