Effect of aeration conditions on aldehyde dehydrogenase activity in yeast cultivation
The culture conditions under aeration affected the reduction ability of yeast strains using ethanol as an energy source. This was caused by changes in the aldehyde dehydrogenase (ALDH) activity, which was demonstrated by measuring the ALDH activities of Saccharomyces cerevisiae and Kloeckera magna. The ALDH activities of these yeasts were maximum at an oxygen absorption rate of 18 mmol/h/l.
