ABSTRACT Spherical Biocatalyst and Process of Producing the Same A spherical biocatalyst is described which con- sists of an immobilized, biologically active material and of an ionotropic gellike matrix, which contains TiO2 having a particle diameter from 0.1 to 1 micrometer. The matrix con- sists of biopolymers. Enzymes, microorganisms or cells are used as a biologically active material. To produce the ca- talyst, an aqueous solution of the substance for forming the matrix is mixed with 7 to 35% by weight TiO2, 0.1 to 20% by weight biologically active material are admixed to the re- sulting mixture, the resulting dispersion is degassed under a pressure from 800 to 10 millibars and the degrassed dis- persion is dripped from a nozzle into a precipitating bath.
