An elongate hollow body (1) comprising crystalline cellulose has on an inside wall a plurality of protuberances (3, 4) which extend into a lumen of the hollow body (1). A process for the production of an elongate hollow body (1) comprising crystalline cellulose comprises the steps: preparation of a hollow mold (12); cultivation of cellulose-forming organisms in an interior space formed by the hollow mold (12), in order to allow the hollow body (1) to grow in the interior space; demolding of the hollow mold (12). In the step of demolding the hollow mold (12), at least part of the hollow mold (12) is irreversibly deformed.
