[Kinetics of growth and development of Mycobacterium rubrum under conditions of periodic culturing].
The kinetics of growth, development, carotenogenesis and changes in the composition of the reaction medium were studied in the course of Mycobacterium rubrum batch cultivation in synthetic and complex media. The culture growth was found to be composed of five phases in the synthetic medium and of four phases in the complex medium. When the culture was grown in the synthetic medium, the phenomenon of distinct diauxy was recorded by changes in the specific growth rate as well as the economic and metabolic coefficients. These growth changes were shown to be associated with the fact that the culture started to assimilate sucrose instead of glucose at the subsequent growth phases, and carbotenogenesis was found to be uncoupled with the period of active biomass and protein synthesis.
