Extracellular polymeric substances are defined as high molecular weight compounds secreted by the microorganisms in the surrounding area. Since these extracellular substances are mainly polysaccharide, they are named exopolysaccharide. Microbial exopolysaccharides composed of sugar residue have growing interest as a new class of microbial products which can be used in food, pharmaceutical, and ...

Exopolysaccharides as well as other bioactive substances of Lactic acid bacteria (LAB) attracted much attention due to its specific structure and functions, e.g. tolerance to gastrointestinal (GI) stress, adhesion on the intestinal mucosa, inhibition against pathogens, and modulation of immune system. In this mini-review, we have summarized the recent progress of exopolysaccharides of Lactobaci...

The endophytic bacterium, MD-b1, was isolated from the medicinal plant Ophiopogon japonicas and identified as the Bacillus amyloliquefaciens sp. with 99% similarity based on the partial sequence analysis of 16S rDNA. Exopolysaccharides were extracted from the endophyte for the evaluation of its antitumor activity against gastric carcinoma cell lines (MC-4 and SGC-7901). 3-(4,5-dimethylthiazol-2...

The medium composition and fermentation conditions of Ganoderma applanatum(GA) strain were optimized by the liquid shake flask fermentation, and the antioxidant activity of exopolysaccharides was investigated. The results showed that the optimal conditions of the liquid fermentation of GA strain were as follows: Carbon source was corn powder, nitrogen source was soy powder, the initial pH was 6...

Exopolysaccharides are high molecular weight polymers of repeated sugar units with diverse chemical structure and unique properties produced by microorganisms. Lactic acid bacteria important exopolysaccharide producers. derived exopolysaccharides, one the postbiotics, known to have technological such as stabilizing, thickening, emulsifing also biological activities. can synthesis exopolysacchar...

Exopolysaccharides get a lot of attention because they can improve the host immune system. Exopolysaccharide is polysaccharide that produced and secreted from microbes outside cell, usually found on bacterial structure. The Lactobacillus casei group human breast milk thought to have ability produce exopolysaccharides. purpose study was examine exopolysaccharide L. isolated milk. methods used in...

Polysaccharides are polymers of carbohydrates with an enormous structural diversity, from long linear repetition of the same monomer to highly branched structures of different sugars. This high structural diversity reflects the functional diversity of these molecules. There are two types of polysaccharides, storage polysaccharides (i.e. glycogen) and structural polysaccharides, which are normal...

BACKGROUND Dental caries is considered a multifactorial disease, in which microorganisms play an important role. The diet is decisive in the biofilm formation because it provides the necessary resources for cellular growth and exopolysaccharides synthesis. Exopolysaccharides are the main components of the extracellular matrix (ECM). The ECM provides a 3D structure, support for the microorganism...
