What are the functions of lactic acid bacteria? The difference between live bacteria and lactic acid bacteria

Lactic acid bacteria is a kind of probiotics that exists in the human body. Lactic acid bacteria can ferment carbohydrates into lactic acid, hence the name. Probiotics can help digestion and contribute to the health of the human intestines, so they are often regarded as healthy foods and added to yogurt. Probiotics represented by lactic acid bacteria are essential to the human body and have important physiological functions. Their number directly affects a person's health and life span. Lactic acid bacteria are very important to human health and longevity.

What are the functions of lactic acid bacteria

Among them, lactic acid bacteria, as an important species of microecological preparations, play an important role in maintaining the intestinal health of humans and animals and promoting the balance of microecology in the body. Its mechanism of promoting human health includes the following four points:

1. Produce antibacterial substances: inhibit the growth of harmful bacteria by producing organic acids, free fatty acids, hydrogen peroxide, bacteriocins, etc.

2. Biological antagonism: Probiotics have colonization properties, limiting the adhesion and colonization of pathogenic microorganisms to the intestinal mucosa.

3. Enzyme action: Increase lactose digestion, modify toxin receptors by producing certain enzymes, and reduce the binding of toxins to intestinal mucosal receptors.

4. Immunity enhancement: stimulate host immune response, enhance humoral immunity and cellular immunity, enhance macrophage phagocytic activity, complement, and reticuloendothelial system function. In simple terms, lactic acid bacteria can promote body growth, improve gastrointestinal function, increase immunity, remove excess free radicals, and delay aging through the various metabolites produced by themselves. Therefore, lactic acid bacteria have great potential application value.

The difference between live bacteria and lactic acid bacteria

Lactic acid bacteria are only effective when they pass through the human digestive organs and are excreted alive. Active lactic acid bacteria can inhibit harmful spoilage bacteria and pathogens by multiplying in the human body. Its metabolism produces lactic acid and effective metabolites (antibacterial substances, vitamins, etc.), and lactic acid bacteria themselves also have the effect of enhancing immunity. Inactive lactic acid bacteria only have the effect of enhancing immunity.

What is Lactobacillus

Lactic acid bacteria are a type of probiotic that exists in the human body. Lactic acid bacteria can ferment carbohydrates into lactic acid, hence the name. Probiotics can help digestion and contribute to the health of the human intestine, so they are often regarded as healthy foods and added to yogurt.

There are hundreds of species of bacteria living in the human intestine, and the number of lactic acid bacteria exceeds one trillion. Among them, those that are beneficial to human health are called probiotics, represented by Bifidobacterium and Enterococcus faecium, and those that are harmful to human health are called harmful bacteria, represented by Escherichia coli and Clostridium perfringens. Probiotics are a large bacterial community, and harmful bacteria are also a large bacterial community. When probiotics are dominant (accounting for more than 80% of the total), the human body remains healthy, otherwise it is in a sub-healthy or unhealthy state. Probiotics represented by lactic acid bacteria are essential beneficial bacteria for the human body and have important physiological functions. Their number directly affects whether a person is healthy or not, and directly affects the length of a person's life. Lactic acid bacteria are very important for human health and longevity.
