An aerobic microbiological method in which a microorganism (2) is immobilized in a fluid-permeable fiber matrix (1) and supplied with a substrate solution (6) and an oxygen-containing gas (10) which are supplied to and leave the matrix as separate flows mutually at an angle of at least 10<o> and are brought into cross-flow contact with each other and with the microorganism (2) within the matrix (1). The fiber matrix preferably consists of mineral wool. The microorganism is immobilized in the matrix by being introduced in a, preferably conically, precompressed matrix which after introduction of the microorganism is further compressed to fix the microorganism in the matrix. Additionally, it is preferred to adjust the volume of the matrix during the course of the microbiological method in dependence upon the growth of the microorganism. This adjustment may be effected such that the pressure drop of the air flow (10) when passing through the matrix (1) is maintained constant. |
