✦ Synopsis

The kinetics of the utilization of D-xylulose by the yeast Schizosaccharomyces pombe has been examined under anaerobic batch conditions.

The inhibitory effect of ethanol on xylulose uptake and ethanol production was studied at pH 6.0 and 30°C.

Ethanol had little or no effect on the sugar uptake rate, but end product inhibition was observed on ethanol production. This non-competitive inhibition was linear with respect to ethanol concentration between 0 and 60 g/l.

A kinetic model for the alcoholic fermentation of xylulose is presented.

In a low dilution rate study an unexpected pa-related inhibition of yeast fermentation was found. A higher volumetric rate of ethanol production occurred at lower pH values (2.8 to 3.2), suggesting a low optimum PH.
