Oligosaccharides and their Effects on Lactobacillus acidophilus
Recently, there have been several reports that demonstrate that oligo-fructose can only increase the number of microorganisms in feces, but cannot promote the number of bifidobacteria in the intestine. Through these experiments, it can be seen that both oligo-maltose and oligo-fructose can promote the proliferation of avian derived Lactobacillus acidophilus, Lactobacillus lactis, and Streptococcus lactis to a certain extent. This enhances the various beneficial effects of lactic acid probiotics such as Lactobacillus acidophilus in the gut promoting a healthy gut microbiome that is low in unwanted pathogenic bacteria.
Oligosaccharides, as bifidogenic factors, cannot be utilized by the digestive tract and pathogenic bacteria, but can only be utilized by probiotics, which can promote the proliferation of lactic acid probiotics and enhance their competitive advantage as growth factors. These experiments observed the effect of isomaltooligosaccharides on the in vitro proliferation of three strains of lactic acid probiotics under different nutritional conditions.
The results of these experiments showed that oligosaccharides can significantly promote the proliferation of lactic acid probiotics such as Lactobacillus acidophilus in nutrient poor culture media, which has positive significance for the intestinal recovery of human and animal organisms in clinical practice. The growth and proliferation of beneficial gut microbiota such as Lactobacillus acidophilus and bifidobacteria require high levels of nutrition, while pathogenic bacteria such as Escherichia coli have relatively low nutritional requirements.
When lactic acid probiotics such as Lactobacillus acidophilus reproduces in the gut of any animal, it is easier to obtain the nutritional requirements for their growth. In a normal and healthy intestinal environment, beneficial bacteria receive sufficient nutrition, grow and proliferate vigorously, and also have a certain inhibitory effect on harmful bacteria; When the body's intestinal tract is disrupted, harmful bacteria proliferate and consume nutrients, while beneficial bacteria like lactic acid probiotics have insufficient nutritional conditions and their growth and proliferation are affected, thereby exacerbating the deterioration of the intestinal environment.
At this time, taking oligosaccharides can effectively exert its proliferative effect on lactic acid probiotics such as Lactobacillus acidophilus, and its characteristic of not being utilized by harmful bacteria determines that it can specifically promote the growth of bifidobacteria and Lactobacillus acidophilus, thereby achieving the effect of regulating the balance of intestinal microbiota.
