Do outer membrane proteins of biofouling bacteria Vibrio alginolyticus have lectins?

The outer membrane proteins (OMPs) of Vibrio alginolyticus, isolated from tin panels lowered into the seawater when subjected to SDS-PAGE analysis revealed proteins of molecular weight ranging from 14 - 116 kDa. However, when stained with PAS only 9 glycoprotein bands were observed. Sugar binding studies and hemagglutination assay performed with RBCs from various animals confirmed the absence of lectins. Apparantely adhesion of V. alginolyticus to tin panels involves other interactions such as Van der Wall's interaction and electrostatic forces.
