Abstract: According to the sources, polysaccharides can be divided into plant polysaccharides, animal polysaccharides and microbial polysaccharides. They not only have the characteristics of high efficiency, low toxicity and wide sources, but also have various physiological functions, such as regulating immune function, anti-tumor, anti-virus, anti-oxidation, anti-diabetes, anti-bacterial and so on. At present, people have been successfully extracted a large number of polysaccharides from higher plants, animal cell membranes and microbial cell walls and they are widely used in food, feed, medicine and other industries. With the continuous development of bacterial drug resistance, polysaccharides have become the focus of research at home and abroad as a class of antibiotic alternatives. This review intends to elaborate on the antibacterial activity and main mechanisms of polysaccharides, in order to provide a theoretical basis for further research on the biological activities of polysaccharides and their mechanism, and to develop safer, greener and more efficient antibiotic alternatives.

Key words: polysaccharides, antibiotic alternatives, antibacterial effect, mechanism of action
