摘要： A bioreactor carrier is provided composed of a water absorption gel of a crosslinked N-vinylcarboxamide resin which has a great moisture content and excellent physical strength, is not eroded by microorganisms and is easily mass-produced on an industrial scale. The gel is obtained by swelling and gelling a crosslinked N-vinylcarboxamide resin made from an N-vinylcarboxamide such as N-vinylacetoamide. The swollen gel may be in the form of beads of 1.0 to 20 mm, and the resin when swollen with water has a water absorption coefficient of 500 to 3500%. Resin beads may be swollen in a suspension of a biocatalyst such as animal cells, plant cells, microorganisms or protozoans to bind and immobilize the biocatalyst to form a bioreactor. The microorganisms can be nitrate bacteria, denitrification bacteria or Hyphomycetes, and the bioreactor may be used to treat waste water or for deodorizing. The crosslinked N-vinylcarboxamide resin contains a repeating unit shown by formula (A) below crosslinked with a crosslinking agent. ##STR1## wherein R.sup.1 and R.sup.2 represent independently a hydrogen atom or a methyl group.

摘要： A bioreactor carrier is provided using an organic polymer substance having a water absorptivity of 50 to 1,700%, and containing an inorganic salt, organic nitrogen source and/or organic carbon source utilizable as a nutrient by animal cells, plant cells and/or microorganisms which fix to the carrier for uses such as substance production, harmful substance treatment, waste oil treatment, wastewater treatment and deodorization. A preferred polymer substance is a water swellable thermoplastic polyurethane gel having the water absorptivity and a swelling rate of volume of 150 to 4,000%. The polyurethane gel is obtained by reacting together a long-chain diol compound, a short-chain diol compound and a diisocyanate compound. The long-chain diol compound has a number-average molecular weight of 400 to 10,000, and is selected from an ethylene oxide-propylene oxide copolymer having an ethylene oxide content not less than 70% and a polyethylene glycol. The short-chain diol compound has a number-average molecular weight of 30 to 400. The diisocyanate compound has a number-average molecular weight of 100 to 1,000 at an NCO/OH equivalency in the range of 1-5. Microorganisms multiply rapidly at the surface and interior of the carrier. Preferred adherence and proliferation of desired microorganisms is possible by appropriately selecting substances incorporated as microorganism nutrients.
