Abstract :A number of different yeasts are now recognized as being capable of fermenting pentose sugar into ethanol. One of the most prominent among these is Pachysolen tannophilus}. The initial yeast extract concentration, D-xylose concentration and pH were chosen as independent factors in 23-factorial experimental design and the effects of these factors on ethanol production from D-xylose by P. tannophilus} were examined in repeated shake flask cultures according to the Box-Wilson experimental design method. A maximum ethanol production rate of 2.03 g dm-3 day-1 was obtained when the initial D-xylose concentration, yeast extract concentration, and pH were 37.01 g dm-3, 8.34 g dm-3, and 4.22, respectively.Keywords : Ethanol production, Pachysolen tannophilus, D-xylose.
