The effect of high oxygen concentration on cell growth and activities of some key enzymes associated with ethanol assimilation was studied by using a Candida sp. Measurements were made at the exponential phase of batch cultures with dissolved oxygen controlled at the levels ranging from 5% to 60% of the saturation concentration with pure oxygen of 1 atm. The results showed the existence of an upper critical value of dissolved oxygen for normal cell growth, above which the metabolism of ethanol assimilation was disturbed and both growth rate and cell yield were reduced. Kinetic examination of the relationship between cell growth and enzyme activities revealed that the reduction of growth rate and cell yield was caused by the depression of the enzyme activities of acetyl-CoA synthetase and isocitrate lyase.
