1. A modular reactor for carrying out biological reactions by means of biocatalysts;

  • comprising;

    a base having an interior space and defining an axis;

    a lid;

    an intermediate section adapted for providing a reaction zone, with said lid constructed so as to be detachably secured to said intermediate section, said intermediate section being constructed so as to be detachably secured between said base and said lid and including a gas bubbles-permeable support member at the junction to said base, said intermediate section being part of a modular kit so as to be replaceable by another intermediate section for allowing selective application of the reactor as a fluidized bed reactor and fixed bed reactor;

    a carrier matrix contained in the reaction zone within said intermediate section above said support member for immobilizing biocatalysts;

    circulation means for circulating a nutrient medium between said interior space and said reaction zone and including a circulation pipe comprised of a pipe traversing said intermediate section in axial direction and an extension pipe provided in said interior space of said base and detachably secured to said pipe in said intermediate section, and an agitating means accommodated in said base for circulating the nutrient medium through said circulation pipe; and

    control means arranged in said base for monitoring and controlling conditions in the reactor for each mode of operation of the reactor.
