Exudate yeasts (700 strains) and newly isolated yeasts (about 1,000 strains) with high glucose tolerance were surveyed for polyol production from glucose. Some exudate yeasts produced about 40% arabitol or glycerol, but they could not grow on high glucose media. Three strains (T-118,O-88 and T-115), selected from new isolates, could grow even on 40% glucose and produced large amounts of polyols. T-18 produced 42.4% glycerol and 23.7% mannitol in a medium (pH 9.0) containing 20% glucose and 0.5% yeast extract. O-88 produced 59.5% arabitol with small amount (5.3%) of glycerol in the same medium. T-115 produced 44.2% erythritol with a small amount (3.5%) of glycerol in a medium (pH 7.0) containing 20% glucose and 0.5% yeast extract. As a result of morphological and biochemical characterizations, T-118,O-88 and T-115 were identified as Torulopsis sp., Brettanomyces sp., and Aureobasidium sp., respectively.
