Abstract: | Candida parapsilosis was grown for 59 h in a medium containing corn cob hydrolysate consisting of 50 g xylose l–1, 3.0 g glucose l–1, 2.0 g arabinose l–1, and 0.9 g acetic acid l–1. A biomass of 9.1 g l–1 was produced with 36 g xylitol l–1 and 2.5 g ethanol l–1. In a medium containing 50 g xylose l–1 instead of corn cob hydrolysate, the concentrations of cells, xylitol, and ethanol were 8.6 g l–1, 33 g l–1, and 0.2 g l–1, respectively. The differences between two cultures were due to the glucose and arabinose in the corn cob hydrolysate stimulating growth and the low concentration of acetic acid stimulating xylitol production. |
