Acetobacter xylinum, which produces cellulose ribbon-like nanofibers with 40-60 nm in width, moves due to the inverse force of the secretion of the fibers. The rate and direction of the movement correspond to those of the fiber production. We reported for the first time the fabrication of cellulose and cellulose triacetate films having a honeycomb-pattern1). It was suggested that the surface structure of the honeycomb-patterned cellulose film is highly ordered, but not crystalline2). In our previous research, it was indicated that this unique structure triggers oriented deposition of various substance3,4). Recently, A. xylinum was found to deposit nanofibers on honeycomb frame only, which turned out to be due to the strong interaction between the nascent nanofibrils and the ordered molecules of the honeycomb frame. In this report, we attempt to fabricate honeycomb-pattened cellulose 3D structures using secreted deposition of cellulose nanofibers from A. xylinum as a building block.
