[Kinetics of continuous growth of a culture of Debaryomyces formicarius in an incubator and continuous-flow columns with a solid phase].

Continuous growth of the yeast Debaryomyces formicarius was comparatively studied in two types of open systems, viz, chemostat and a continuous-flow column packed with sand. The dynamics of concentrations of growth substrates and microbial biomass was assayed in the column and in the column eluate in the conditions of carbon and nitrogen limitation. A kinetic model for microbial growth in the continuous-flow column is proposed; the model is based on the assumption that the microbial population contains free and immobilized cells which differ sharply in their metabolic activity. Principal differences in the kinetics of microbial growth in continuous-flow columns as compared to that in chemostat are discussed.
