I am came across a publication "Physicochemical investigations of biogenic chitosan-silvernanocomposite as antimicrobial and anticancer agent" International Journal of Biological Macromolecules 92 (2016) 77–87.
The Abstract first line says "Chitosan (CS), a seaweed polysaccharide is a natural macromolecule which is widely being used in medical applications because of its distinctive antimicrobial and anticancer properties.
I would ike to know if there is any seaweed producing Chitosan?
I think Chitosan is produced commercially by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans (such as crabs and shrimp) and cell walls of fungi (wikipedia)
Hi,
So far, depending on the type of seaweed, Rhodophyta, Chlorophyta or Ochrophyta-Phaeophyceae, what has been identified by seaweed polysaccharides are: carrageenan, agar, ulvans, alginate, fucoidan, laminarin besides the cellulose from the cell wall.
You can check the following:

Dear CRK Reddy I agreed with your comments. But recently a group from Anna University of Technology, Department of Chemistry and other published https://www.researchgate.net/publication/304779913_Physicochemical_investigations_of_biogenic_chitosan-silver_nanocomposite_as_antimicrobial_and_anticancer_agent labeling chitosan as marine seaweed polysaccharides
