PURPOSE: To provide a method for efficiently producing D-arabitol, and a method for producing D-xylulose and xylitol using the method. CONSTITUTION: The method for producing xylitol comprises the steps of: producing D-arabitol in a medium by culturing a microorganism which belongs to the genus Metschnikowia, and can produce D-arabitol (e.g. M pulcherrima, M reukaufii, M bicuspidata, M. lutana, and M. zobellii) aerobically in a medium containing saccharide(s) as the main carbon source(s) to form D-arabitol in the medium, inoculating/culturing a microorganism which has an ability of producing D-xylulose from D-arabitol to form D-xylulose in the broth, and inoculating/culturing a microorganism which has an ability of transforming D-xylulose to xylitol to the broth containing D-xylulose to collect xylitol formed.
