Abstract: | A xylose-utilizing bacterial strain was isolated from soil.The strain, No. 553, was identified as Enterobacter liquefaciens from the result of the taxonomical studies. This bacterium grew well on D-xylose as a sole carbon source and accumulated pentitol extracellularly in shaking culture.Pentitol produced was isolated from the culture broth and identified as xylitol.The xylitol production reached the maximum after the cessation of the cell growth with a yield of 33.3 mg per ml in a medium containing 10% D-xylose as a sole carbon source and no significant decline of the amount of xylitol was observed through the period of the cultivation. |
