Abstract

A method for treating an organic and/or inorganic substrate utilizing a granular material made of a solid foam as support for an active component, for example a biocatalyst such as a microorganism or an enzyme. The solid foam has a continuous phase in which magnetizable particles are embedded, such that the support with the biologically active component immobilized thereon can be separated from a mixture with a magnetic separation device.
