Abstract
A technique for producing microbial cellulose is provided, including: preparing a liquid medium for microbial cultivation in a container; horizontally rotating multiple hollow tubes that are fitted together or separated from one another, so that each of the hollow tubes is alternately partially immersed in the liquid medium and partially exposed above the horizontal surface of the liquid medium; wherein each of the hollow tubes has a rough outer surface and a smooth inner surface, so as to allow microorganisms to form microbial cellulose on the outer surface of each hollow tube, as well as forming sheets of microbial cellulose on the horizontal surface of the liquid medium not being disturbed by the hollow tubes, and removing the microbial cellulose from the outer surfaces of the hollow tubes in order to obtain tubular microbial cellulose. In addition, the sheets of microbial cellulose are also harvested from the liquid medium.
