PURPOSE:To produce a sugaralcohol solution to be readily purified without causing by-products, by treating yeast belonging to the genus Candida immobilized to a carrier with a mixed saccharide solution of substrate saccharide and hydrogen donor saccharide. CONSTITUTION:Yeast such as Candida tropicalis or Candida utilis, belonging to the genus Candida is cultivated and the yeast is immobilized to a ceramic carrier, a gelatinous carrier such as gelatinized polyacrylamide or gelatinized alginic acid or a polyurethane foam carrier. The immobilized yeast packed into a reactor is reacted with a mixed saccharide solution comprising a substrate saccharide such as glucose or mannose, a hydrogen donor saccharide such as glucose or galactose and a nutritive source for yeast by passing the solution through the reactor. Consequently a sugaralcohol corresponding to the substrate saccharide is obtained. |
