Abstract
A new method of evaluation of the aeration capacity, kLa from data measured with the use of an oxygen electrode was proposed, based on the algorithm of adaptive identification. In this way, even the time dependence of kLa in the course of a dynamic experiment can be obtained. The results from mechanically stirred fermentors and apparatuses of the bubbled column type show that the commonly used assumption about the time independence of kLa does not hold for intensively aerated apparatuses.
