摘要

PURPOSE:To provide the titled molding material having excellent tensile strength, expansion resistance, elasticity, etc., containing bacterial cellulose composed of ribbon-form microfibrils. CONSTITUTION:A bacterial cellulose-producing strain of the microorganism of the Genns Acetobacter, Pseudomonas or Agrobacterium is cultured, and gel is isolated from the cultured medium contg. produced bacterial cellulose, purified and squeezed from the perpendicular direction under a pressure of 1-10kg/cm2 to obtain bacterial cellulose wherein ribbon-form microfibrils are entangled. If desired, bacterial cellulose is macerated, stuck on a support such as glass sheet and dried to obtain a sheet of 1-500mu in thickness. The sheet is impregnated with a soln., an emulsion or dispersion of at lest one fixing immobilization support material selected from among hydrophilic and hydropho bic high-molecular materials, metal, inorg.materials, coupling agents, adhesives and antimicrobial agents to obtain the titled molding material having a bacterial cellulose content of 0.01-100%.
