SummaryWhen Candida tropicalis fermented xylose under oxygen limited conditions in the presence of increasing concentrations of polyethylene glycol (PEG), the ethanol production increased by a factor of two and the xylitol production was repressed by about 25%. Xylose assimilation and cell growth were not affected by the presence of PEG. The fermentation of glucose was not as strongly influenced by the presence of PEG as were xylose fermentations. The results are discussed in relation to the… CONTINUE READING
