Cultural conditions for erythritol production by Aureobasidium sp. SN-115,were examined. On the basis of glucose consumption, this strain produced about 45% erythritol and a small amount of glycerol.Aureobasidium sp. SN-115 had good yiedls at pH between 5 and 6,and from 34 to 38℃. This strain produced erythritol from sucrose, fructose, and mannose in addition to glucose. When 0.05% sodium sulfate was added to the medium, the highest yield of about 51% was obtained, and with 0.025% aluminum chloride (6 hydrates), formation of glycerol was completely repressed.Foam was a problem when this strain was cultured in a fermentor with agitation, but, from the results obtained with polysaccharides, emulsifiers, and surface active agents tested, it was found that Triton N-101 made it possible to culture this strain in a common, large-scale fermentor.
