[Approximation of time-profiles of pH alteration by cells of Candida tropicalis by means of reactions of hypothetical linear object with negative feed-back].
The autostabilization of the environment pH value in batch cultures of yeast Candida tropicalis was experimentally investigated. The pH alternation had unidirectional compensatory nature, which allowed to represent the reaction of the system as the reaction of hypothetical linear object with negative feed-back. The transmission functions of structural elements of this object were determined. It was shown that such a model describes experimental data quite well in a wide range of initial environment pH values.
