Özet:

 

The fermentative ability of Candida tropicalis Kuen 1022  yeast to produce xylitol from D-xylose and sunflower seed hull  hydrolyste was examined under aerobic conditions.  In batch cultures  having a synthetic xylose concentrations ranging from 50 gl-1 to  100 gl-1,the maximum xylitol yield achieved was 0.26 g/g xylose  consumed with a volumetric rate of xylitol production of 0.196  gl-1h-1 when the initial synthetic sugar concentration was 50  gl-1.  The pretreated sunflower seed hull hydrolysate was  cultivated with the previously hydrolysate medium adapted yeast cells.   The maximum xylitol concentration was 4.72 gl-1, the fermentation  time was 96 h, xylitol yield was 0.113 g/g xylose consumed and  volumetric productivity was 0.219 gl-1h-1 for hydrolysate having  an initial composition of xylose 66 gl-1 and glucose 0.8 gl-1.
