Ethanol Accumulation in Cultures of Pachysolen Tannophilus on D-Xylose is Associated with a Transition to a State of Low Oxygen Consumption

Bio/Technologyvolume 3pages5962 (1985) | Download Citation



Ethanol accumulation in aerobic batch cultures of Pachysolen tannophilus growing on D-xylose is associated with a transition to a state of low oxygen consumption, and the events triggering the accumulation differ from those of a Crabtree effect. The transition explains the accumulation of ethanol at only a particular interval during the growth of the culture, shows that such accumulation is not dependent on limited oxygen supply, and offers approaches to enhancing the yield of ethanol.
