Fed-batch cultivations of Pichia stipitis and strains of Candida shehatae with d-xylose or d-glucose were conducted at controlled low dissolved oxygen tension (DOT) levels. There were some marked differences between the strains. In general growth was inhibited at lower ethanol concentrations than fermentation, and ethanol levels of up to 47 g·l-1 were produced at 30°C. Ethanol production was mainly growth associated. The yeast strains formed small amounts of monocarboxylic acids and higher… CONTINUE READING
