Lactobacillus rhamnosus is mostly found in the intestines of humans and animals. It belongs to the genus Lactobacillus, subspecies rhamnosus in bacterial taxonomy. It is an anaerobic, acid-resistant, non-spore-forming Gram-positive probiotic. Lactobacillus rhamnosus cannot utilize lactose, but can ferment a variety of monosaccharides (glucose, arabinose, maltose, etc.). Most strains can produce a small amount of soluble ammonia, but do not produce indole and hydrogen sulfide. It has biological characteristics such as acid resistance, bile salt resistance, and resistance to multiple antibiotics.
Lactobacillus rhamnosus (Lactobacillus rhamnosus), freeze-dried bacterial powder processed by freeze-drying technology, auxiliary materials include bacterial culture medium and protective agent. The product is powdery, without visible impurities, and the color is white to light yellow. It can be widely used in food, dairy products and functional health products.
Lactobacillus rhamnosus GG (abbreviated as Lactobacillus GG or LGG) was isolated from a healthy human body by two professors (Gorbach and Goldin) at North Carolina State University in the United States in 1983 and patented.
The Functional Characteristics of Lactobacillus Rhamnosus
Regulate intestinal flora
After LGG colonizes and reproduces in the human intestinal environment, it only attaches to the host's intestinal epithelial cells and can become a biological barrier of the intestinal mucosa, thereby improving the host's intestinal mucosal barrier capacity. Moreover, with the help of LGG, the structure and function of the microecological community in the host's intestine can be regulated and balanced, thereby achieving the purpose of improving the function of the host's digestive system. Relevant studies have shown that the adhesion rate of LGG to adults is significantly higher than that of children, mainly because the intestinal environment of adults is more mature and suitable for LGG adhesion.
Enhance the body's immunity
The human immune system can be divided into innate and adaptive immune systems. The innate immune system is mainly undertaken by macrophages, leukocytes, etc. If the innate immune system is dysfunctional, the adaptive immune system will function. The two work together to complete the immunity of the human body. Once the host is traumatized and infected, it will cause immune system dysfunction.
Prevention and treatment of diarrhea
LGG can be used to prevent and treat diarrhea. Relevant studies have shown that LGG bacteria were detected in the feces of 29 infants who took LGG preparations and ordinary cow's milk orally. This shows that after taking it, the host uses LGG to regulate the intestinal flora, and the treatment effect of diarrhea in infants taking LGG preparations is better than that of taking ordinary cow's milk.
