Scytonema varium is a cultured cyanobacterium of the genus Scytonema [1] It is one of many anti viral protein producing algae. In a similar manner to Cyanovirin-N from Nostoc Ellipsosporum and griffithsin from the red algae Griffithsia, Scytonema varium secretes the broad-spectrum antiviral protein scytovirin which can inactivate both the HIV virus,[1] and Ebola virus,[2] offering hope of treatment for many diseases with viral etiology (cause). It is currently being investigated as a topical microbicide for HIV prophylaxis.[3]
