Abstract

In fermentation processes the mass of micro-organisms present, the biomass, is concentrated by coagulation of the solids of the fermentation suspension by the action of an electric current having a frequency of from 0 to 2000 Hz, up to a current density of 10 mA/cm<2>, at a temperature of from 20 to 100 DEG C.
