Abstract

Acetobacter xylinum, a bacterium which secretes a cellulose nanofiber, moves due to the inverse force of extrusion of the fiber, which accordingly correlates with the fiber production rate. To improve the production, the moving rate of the bacterium was focused to examine the influential factors on the substrates for culture and additives in the culture medium. From the real-time video analysis, the oriented template having a strong interaction with the secreted cellulose nanofibers proved to be suitable for the bacteria to move faster. Furthermore, addition of carboxymethylcellulose sodium salt (CMC) to the culture medium cause the bacteria to move faster in the culture medium. In this case, secreted cellulose nanofiber formed different from a normal cellulose nanofiber. The above result could provide an understanding how the formation of cellulose nanofibers contributes to the production rate as well as the bacterial moving rate.
