In the conventional techniques for converting lactose contained in a whey into xylitol, a process for converting lactose into glucose and galactose with β-galactosidase is absolutely necessary, and the glucose is then converted into arabitol During the process, the reaction product may be contaminated with unreacted glucose or undesired galactose as an impurity, and therefore a procedure for separating the unreacted glucose or undesired galactose is also required Thus, the object is to develop a method for converting lactose into arabitol directly, which can prevent the production of glucose or galactose and which does not need any procedure for separating impurities A novel yeast strain is now found, which enables the conversion from lactose into arabitol
