Concurrent Production and Consumption of Ethanol by Cultures of Pachysolen tannophilus Growing on d-Xylose †

摘要: Growing cultures of Pachysolen tannophilus concurrently consumed and produced ethanol in the presence substantial concentrations d-xylose. Ethanol was also assimilated other sugars, amount depending on sugar. Less assimilation occurred with d-glucose than The rate consumption decreased as concentration glucose increased, but some still when 2% present. increased oxygen available to culture d-xylose or carbon source. In most instances, estimates were based extent incorporation 14C from [1-14C]ethanol into trichloroacetic acid-insoluble material. results are pertinent use P. for production
