Why do bacteria produce Exopolysaccharides?

Why do bacteria produce Exopolysaccharides?

Exopolysaccharides (EPSs) are biological polymers secreted by microorganisms including Lactic acid bacteria (LAB) to cope with harsh environmental conditions.

What is lactic acid bacteria lab used for?

Lactic acid bacteria are used in the food industry for a variety of reasons such as the production of cheese and yogurt products. This process has been going on for thousands of years by human ancestors. But, some of the beverages we enjoy today are produced by using lactic acid bacteria.

How are Exopolysaccharides produced?

Exopolysaccharides (EPSs) are formed monosaccharide residues of sugar and sugar derivatives. They are produced by plants, algae, fungi and bacteria [1]. Deep-sea hydrothermal vents, Antarctic ecosystem, saline lakes and geothermal springs are extreme environmental and several microorganisms isolated from these areas.

What is the importance of lactic acid bacteria serum?

Some of the health benefits which have been claimed for lactic acid bacteria as probiotics include the following: improvement of the normal microflora, prevention of infectious diseases and food allergies, reduction of serum cholesterol, anticarcinogenic activity, stabilization of the gut mucosal barrier, immune …

What are Exopolysaccharides made of?

Exopolysaccharides generally consist of monosaccharides and some non-carbohydrate substituents (such as acetate, pyruvate, succinate, and phosphate). Owing to the wide diversity in composition, exopolysaccharides have found diverse applications in various food and pharmaceutical industries.

What do Exopolysaccharides do?

Exopolysaccharides (EPS) are extracellular macromolecules excreted as tightly bound capsule or loosely attached slime layer in microorganisms. They play most prominent role against desiccation, phagocytosis, cell recognition, phage attack, antibiotics or toxic compounds and osmotic stress.

How do lactic acid bacteria lab beneficial to human beings?

Most of them are normal flora of human being and animals and produce myriad beneficial effects for human beings include, alleviation of lactose intolerance, diarrhea, peptic ulcer, stimulation of immune system, antiallergic effects, antifungal actions, preservation of food, and prevention of colon cancer.

What are exopolysaccharides made of?

What do exopolysaccharides do?

How is lactic acid bacteria beneficial?

There are several potential health or nutritional benefits possible from some species of lactic acid bacteria. Among these are: improved nutritional value of food, control of intestinal infections, improved digestion of lactose, control of some types of cancer, and control of serum cholesterol levels.

How does lactic acid benefit us?

Lactic acid and the bacteria that produce it are associated with several health benefits, including improved gut health and increased nutrient absorption. Lactic acid may also act as an antioxidant to protect against cell damage and chronic disease.

What are bioactivities of exopolysaccharides of lactic acid bacteria?

The ability to exhibit various bioactivities is widespread in exopolysaccharide (EPS) of lactic acid bacteria (LAB), and it has been admittedly associated with large structural variability of these polymers. Exceptional bioactivities such as cholesterol-lowering, immunomodulating, antioxidant, antiv …

What are the health benefits of lactic acid bacteria?

Among the various lactic acid bacteria, exopolysaccharide (EPS) producing strains are known to provide a variety of health benefits for their hosts (e.g. anti-inflammatory, antioxidant, antitumor and stress tolerant effects).

Where does lactic acid bacteria ( LAB ) colonize?

Lactic acid bacteria (LAB) are known to have a significant ability to colonize the human intestinal tract and adhere to the surface of intestinal epithelial cells.

Is the EPs from the lab biofunctional?

Multiple groups have reported that EPS from LAB has significant biofunctional properties and its functionality varies depending on structure and the bacterial strain which produced it.
