Summary Xylose metabolism by Candida shehatae in continuous culture was examined under both fully-aerobic and semi-aerobic conditions. Growth did not occur in the absence of respiration. Under fully-aerobic conditions, the cell yield was constant at 0.51 g/g and the specific respiration rate Q o 2 was linearly related to the specific growth rate μ with a slope of 15 mmol g-1 and an intercept of 1.2 mmol g-1 h-1. Under semi-aerobic conditions, Q O 2 was proportional to μ with a slope consistent with a cell yield from oxygen Y O 2 of 35±7 g mol-1. The specific xylose uptake rate was a constant independent of μ and equal to the maximum rate of xylose transport. Ethanol production was observed under semi-aerobic conditions only, and the specific fermentation rate was inversely related to μ.
