摘　　要：分离筛选到了一株产赤藓糖醇能力高的菌种B84 5 ,通过对B84 5的形态、生理生化特性试验 ,发现该菌耐高渗 ,能发酵葡萄糖、蔗糖、麦芽糖 ,细胞为圆形、椭圆形 ,单边或多边芽殖 ,有真菌丝 ,在固体培养基上培养 7d后颜色开始变深 ,由黄色变成褐黑色 ,参阅真菌鉴定手册 ,初步鉴定为圆酵母属菌 (Torulasp.)A strain B845 with high productivity of erythritol was screened from nature.Through morphological study,biophysical and biochemical tests,we discovered that this strain was a kind of osmophilic yeast and can fermented glucose,sucrose and maltase.Its cell was round or ellipse shape with real mycelium,reproducted by unilateral or multilateral budding.After cultivating in solid medium for 7 days,its colonies turned from yellow to brown.So according to Hand Book of Fungus Identification,this strain was determined to be Torula sp.
