Physiological aspects of intensifying yeast growth

The possibilities of intensifying yeast growth during flow cultivation via an increase in the rate of medium flow and the concentration of carbon-containing substrate are considered. It is found that stabilization of the optimum specific substrate loads provides the maximum economic coefficient of the process. Stabilization of the optimum specific loads of carbon-containing substrates during a three-stage flow cultivation of yeasts in a medium with n-alkanes allowed the throughput of a battery of fermenters to be elevated 1.84-fold. Alternation of flow chemostatic and turbidostatic yeast cultures was accompanied by a fivefold increase in the maximum specific growth rate.
