Constructing zwitterionic nanofiber film for anti-adhesion of marine corrosive microorganisms.

A zwitterionic nanofiber film was constructed through combining zwitterionic polymer with anodic aluminum oxide template for anti-adhering typical marine corrosive microorganisms, i.e. Pseudomonas aeruginosa , Desulfovibrio vulgari s and Chaetoceros muelleri. Results showed that the fabricated zwitterionic polymers film has fibrous nanostructure with uniform distribution and super hydrophilia. This film has wide anti-adhering properties, and it can effectively reduce the attachment of these three microorganisms by more than 99%. Moreover, the adhesion of extracellular polymeric substances secreted from these three microorganisms are also inhibited, which is one reason for the fabricated nanofiber film with anti-adhesion characteristic of microorganisms. This research provides valuable information for solving the problem of microbial adhesion on metal surfaces in the marine environment. [ABSTRACT FROM AUTHOR]
