Abstract

The development of the modern biotechnology products is determined largely by the introduction of new technologies, including the biotechnology, based on the use of biological agents for the synthesis of new products. The use of biological agents in industrial processes is possible to create favorable conditions (temperature level, substrate transport, removal of metabolic products) for their activity in the industrial equipment, namely, in fermenters. To provide the favorable conditions various ways of stirring are applied.

The process of stirring in the fermenter is studied for cultivation of biological agents, sensitive to the action of shear stresses. The experiments are based on the definition of time of homogenization and determination of power spent on the stirring. The results obtained during the experiment are presented and the graphic dependencies are built. The experiments permit to assess the hydrodynamic conditions in the fermenter, in particular the intensity of the stirring
