(2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal → D-Arabitol

Reaction Steps

As can be seen from the results in Table 6, when the production of xylitol was performed through fed-batch culture using the new mutant strain, xylitol was produced for 72 hours was produced in a concentration of 201.3 g/L for 72 hours, suggesting a xylitol yield of 97% and a xylitol productivity of 2.80 g/L/h. Glucose contained in the corncob hydrolyzate was completely consumed during the cell culture process, and 23.7 g/L corresponding to 85% of the total amount (27.9 g/l) of arabinose added remained as arabinose, and 4.2 g/L corresponding to 15% was converted to arabitol. Herein, the concentration of final xylitol concentration (201.3 g/L) to arabitol concentration (4.2 g/L) was 100:2.1, resulting from a decrease arabitol production of 65% compared to the parent strain.
