| Research Abstract |
This project deals with an attempt for proposing a novel nano-fiber spinning process. The concept was based on formation of hierarchical structure of higher plant cell walls from cellulose molecules through nanofibers till micro-sized bundle to be deposited as 2-dimensional walls.
The micro-sized channels were employed as a limited and flow field for controlled culturing of an aerobic bacterium, Gluconacetobacter xylinus, which secrete a cellulose nanofiber into the culture media. When cultured in fact, an assembly of just secreted nanofibers from the individual bacteria was induced to result in formation of a larger nano-bundle of the initial nanofiber, by controlling movements of the bacterium in the channel.
