Nj. Cao et al., THE EFFECT OF CELL-DENSITY ON THE PRODUCTION OF XYLITOL FROM D-XYLOSEBY YEAST, Applied biochemistry and biotechnology, 45-6, 1994, pp. 515-519
The rate of xylitol production from D-xylose increased with increasing
yeast cell density. The optimal temperature for xylitol production is
36 degrees C, and the optimal pH range is from 4.0 to 6.0. At high in
itial yeast cell concentration of 26 mg/mL, 210 g/L of xylitol was pro
duced from 260 g/L of D-xylose after 96 h of incubation with an indica
ted yield of 81% of the theoretical value.
