Japanese "Mozuku" dish

Cladosiphon okamuranus (モズク;水雲;藻付;海蘊;海雲, mozuku) is a type of edible seaweed in the genus Cladosiphon, naturally found in Okinawa, Japan. Most mozuku is now farmed by locals, and sold to processing factories. The main use of mozuku is as food, and as a source of one type of sulfated polysaccharide called Fucoidan, which is used as a cancer treatment aid and health supplement.

Mozuko biology[edit]

A group of researchers conducting DNA research decoded S-strain genome for cladosiphon okamuranus and found that its size was roughly 140 Mbp and smaller relative to other brown alga. They also made a rough estimate on the number of genes C. okamuranus has and found 13,640 genes. [1].
