Portunus is a biomanufacturing firm producing chitosan and chitosan oligosaccharide liquid to be used as an antifungal spray on crops. Our practice is to take a waste product from seafood processing and mushroom growth and use naturally occurring microorganisms to process the chitin in that waste product to chitosan. Our process mimics naturally occurring bacterial decomposition and infection of crustaceans in the disease known as “shell rot.”



Portunus addresses Sustainable Development Goals: Zero Hunger (#2), Good Health and Well-Being (#3), Responsible Consumption and Production (#12), Life on Land (#15).
