[Growth kinetics model of the oxytetracycline producer taking into account the concentrations of 2 substrates].

The effect of starch and ammonium sulphate on the growth of the oxytetracycline-producing organism was studied using the procedure of acute experiments. It was proposed to use a mathematical model for description of the dependences taking into account the possibility of limiting or suppressing the growth of the culture by any of the above substrates as dependent on their ratio in the medium. Satisfactory confirmity of the model to the experimental data was shown. It was noted that similar models may be successfully used for description of such dependences as curves with flat plateau in the region of the maximum which are often met in microbiological processes.
