Probiotics are mainly divided into four types: lactobacilli, gram-positive bacteria, bifidobacteria, and yeast. Different types of probiotics have different effects.
1. Lactobacillus mainly includes Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus casei and other drugs. These probiotics can secrete lactic acid and acetic acid, which are beneficial to enhance the body's immunity, maintain the health of intestinal flora, and also inhibit the growth of mold. Among them, Lactobacillus rhamnosus can tolerate the digestive tract environment and can relieve the symptoms of lactose intolerance.
2. Gram-positive bacteria include Bacillus cereus, Enterococcus faecalis, etc. Bacillus cereus has bacteriostatic effect and can control infection; Enterococcus faecalis can form biofilm on intestinal epithelial cells and protect intestinal epithelial cells.
3. Bifidobacterium species include Bifidobacterium longum, Bifidobacterium infantis, and Bifidobacterium breve. Bifidobacteria can regulate the intestinal flora and have a bidirectional regulating effect on the intestinal tract, that is, it can be used for the treatment of constipation and can also relieve diarrhea.
