Abstract:

Lactic acid bacteria are acknowledged as one kind of food-grade probiotics, and play an important role in medical
science, food science and many other fields of life science. Extracellular polysaccharide as the extracellular secretion of
lactic acid bacteria is closely related to its biological characteristics. This article reviews the immune regulation mechanism,
physical and chemical properties, and molecular structure of extracellular polysaccharides from lactic acid bacteria, and
summarizes their gastrointestinal and immune regulatory effects. We expect that this study will provide the theoretical basis
for researching and applying exopolysaccharides from lactic acid bacteria.

Key words: lactic acid bacteria, extracellular polysaccharide, adhesion, immunoregulation
