摘要：
The present invention relates to an improved method for the preparation of hollow cellulose vessels produced by a microorganism, and hollow cellulose vessels prepared by this method. The method is characterized by the culturing of the cellulose-producing microorganisms being performed on the outer surface of a hollow carrier, and providing an oxygen containing gas on the inner side of the hollow carrier, the oxygen containing gas having an oxygen level higher than atmospheric oxygen. The hollow microbial cellulose vessels of the present invention are characterized by improved mechanical properties and can be used in surgical procedures to replace or repair an internal hollow organ such as the urethra, ureter, the trachea, a digestive tract, a lymphatic vessel or a blood vessel
