PURPOSE:Ultrafine fibers are formed from aminoacetalized PVA and a water- soluble amorphous polymer and dipped in an aqueous solution containing microorganism cells to permit simple formation of cell body-immobilized fibers showing high enzymatic activity. CONSTITUTION:A dope containing aminoacetalized polyvinyl alcohol and a water-soluble amorphous polymer is subjected to dry spinning. The resultant filaments are rinsed with water to effect the selective elution of the amorphous polymer to give ultrafine fibers. Then, the ultrafine fibers are freeze-dried, then dipped in an aqueous solution containing cell bodies of a microorganism. As the microorganism, is cited bread yeast, glucose isomerase filamentous fungi, aminolactamase-producing fungi, penicillin-producing fungi, streptomycin-producing fungi, melibiase-producing bacteria, glucose oxidase-producing bacteria or Aspergillus. |
