Intensification and optimization of processes applied in industries cultivating microorganisms.Peer-reviewed article

V. ŠIMEK

The article deals with some problems connected with the cultivation of microorganisms on an industrial scale, especially with the recirculation of medium and intensification of processes, i. e. with problems touched already in [1, 2]. In the first part of the article the author outlines specific features of cultivation in plants with full-scale circulation of medium. Mass balance resulting from biochemical processes taking place in fermenters is calculated both for cultivated microorganisms and other components. Concentration changes of components are time dependant and can be described by exponential formulae. In the second part limits of intensification are specified for individual components. Goad results can be achieved in fermenters for continuous cultivation operating with partial medium recirculation. Intensification degree is measured by recirculation rate. Closing paragraphs deal generally with various methods of cultivation in recirculating plants. Time dependant concentration changes for discussed methods are specified in a number of formulae.
