Acinetobacter sp. Tol 5 is a hydrocarbon-degrading bacterium and exhibits noteworthily high adhesiveness to various abiotic surfaces from hydrophobic plastics to hydrophilic glass and metals. This unique nonspecific adhesiveness is mediated by AtaA, a nanofiber protein on the cell surface. The photograph shows a fluorescent microscopic observation of mCherry-expressing Tol 5 cells stained with an anti-AtaA antibody. The cell body of Tol 5 (red) wascovered with surrounding AtaA fibers (green).
