General Description

Curdlan is a high molecular weight polysaccharide consisting of β-1,3-linked glucose units, produced by pure-culture fermentation from a non-pathogenic and non-toxicogenic strain of Agrobacterium biovar 1 (identified as Alcaligenes faecalis var. myxogenes at the time of discovery) or Agrobacterium radiobacter. Curdlan consists of β-(1,3)-linked glucose residues and has the unusual property of forming an elastic gel upon heating its aqueous suspension.
