Curdlan (or Beta˜1,3˜glucan) is a high molecular weight polymer of glucose. Curdlan consists of β˜(1,3)˜linked glucose residues and forms elastic gels upon heating in aqueous suspension.It is produced by Agrobacterium biobar, a non pathogenic bacteria. The production of curdlan by Alcaligenes faecalis is being developed to be used in gel production as well.

1. In the food industry applications: Curdlan used for meat processing, the application in the pasta products, the application in aquatic products, the application in baking products, the application in frozen products, the application in other products, such as Strawberry jam, honey and mayonnaise and other sticky and easy to operate flavor.
2.In the chemical industry: Curdlan packing used in the chemical industry is generally dextran. Some scientists have studied the use of coagulation polysaccharide instead of dextran as a column packing, and achieved a better separation.
