PURPOSE:To produce efficiently sorbitol, by cultivating a specific strain belonging to the genus Cephalosporium in a culture medium containing a pentose as a main carbon source, and bringing the resultant culture into contact with glucose. CONSTITUTION:Cephalosporium species U-29 (FERM-P No.7261) is newly separated from soil. The resultant fungus is cultivated in a culture medium containing 2-15% pentose such as D-xylose, D-arabinose or D-ribose as a carbon source and other nutrient sources under aerobic conditions. The resultant microbial cells, crushed microbial cells or extracts are added to a glucose solution in 1-60% concentration and reacted therewith at 10-60 deg.C, preferably 25-35 deg.C to produce the aimed sorbitol. |
