[Use of a control electropneumatic device for studying the cyclic changes in yeast cultivation conditions].
A standard fermenter supplied with an additional electropneumatic device can be used to control stepwise changes of pO2, pH, temperature and rpm according to a preset programme in minute time intervals. This is illustrated with the data obtained upon Candida utilis cultivation under the conditions of 10-min cyclic changes in pH 4.5 leads to 2.6 leads to 4.5 and 4.5 leads to 7.5 leads 4.5. The yeast is resistant to abrupt and frequent changes in the pH of the medium.
