Abstract

This paper describes rapid fabrication of bacterial cellulose (BC) microfibers using cellulose producing bacteria, Acetobacter xylinum. We successfully fabricated BC microfibers (100-200μm in diameter)consists of cellulose nanofibrils by sealing and culturing A. xylinum within the core of the hydrogel fiber. The BC microfibers were formed within 24 - 48 hours after the fabrication. This process is remarkably fast considering the conventional method takes 3-7 days to obtain BC scaffolds. The cellulosic biofilm retain its structure even after removal of the shell. We found that the our microfibers have high potential as micro-scaffolds for making "cell tube".
