NOVELTY - Shewanella-immobilized nanocellulose composite membrane comprises Shewanellawhich forms membrane on the nanocellulose composite membrane. The nanocellulose composite membrane is a graphene-nanocellulose composite membrane. The metal is deposited on the graphene. USE - The membrane is useful for degrading organic pollutants in industrial organic wastewater (claimed). ADVANTAGE - The method does not require organic solvents, toxic and harmful reagents; has simple preparation method, mild reaction conditions and is environmental friendly and economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing -immobilized nanocellulose composite membrane comprising (a) preparing mixed culture medium containing graphene oxide, (b) adding to the mixed medium obtained in step (a), culturing to form a graphene oxide-nanocellulose composite membrane, (c) heating the graphene oxide-nanocellulose composite membrane, adding auxiliary reducing agent to reduce the graphene oxide-nanocellulose composite membrane to a graphene-nanocellulose composite membrane, (d) preparing the mixed solution containing silver ion and wet cells, (e) placing the obtained graphene-nano cellulose composite film in the mixed solution, reacting, realizing the reduction and deposition of silver ions on graphene while immobilizing on the graphene-nanocellulose composite membrane and (f) washing the product to obtain the nanocellulose composite membrane immobilized with ; andShewanellaAcetobacterShewanellaShewanellaShewanella use of nanocellulose composite membrane as a bacterial carrier comprising nanocellulose composite membrane loaded with graphene and the graphene is loaded with metal.
