ABSTRACT:
A bioreactor carrier is provided which is a thermoplastic organic high molecular compound having a swelling rate of volume in water of 150-4,000% and which is useful as a carrier to which animal cells, plant cells, microorganisms and/or protozoans are fixed to obtain a bioreactor for substance production, harmful substance treatment, waste oil treatment, wastewater treatment, deodorization or the like. A method of producing the carrier includes the steps of reacting long-chain and short-chain polyol compounds and an isocyanate compound to obtain a thermoplastic resin, heating the thermoplastic resin to its melting temperature thereby plasticizing it, extruding the plasticized resin into strands with an extruder, and continuously chopping the strands into pellets.
