    摘要： Biologically pure culture of Aureobasidium sp. SN-124A strain (FERM BP-1429) and artificial mutants thereof according to the present invention show the properties of forming and accumulating erythritol in a culture solution, when aerobically cultured on a liquid culture medium containing an assimilable carbon source and an assimilable nitrogen source, and are useful for the preparation of erythritol by fermentation of sugars. A method for preparing erythritol by fermentation of sugars according to the present invention comprises inoculating microorganism selected from the group consisting of Aureobasidium sp. SN-124A strain (FERM BP-1429) and mutants thereof on a liquid culture medium of pH 4 to 9 containing an assimilable carbon source and an assimilable nitrogen source, and aerobically culturing them at a temperature of 30.degree. to 38.degree. C. to form and accumulate erythritol in said culture medium for collection.
