The present invention is a red yeast 2-14 (Rhodotorulasp.2-14) CGMCC? NO.4445?. Red yeast 2-14 cells were round or oval, the size of 4.5~5.1 * 6.3~7.2 m, the mode of reproduction for budding, no pseudomycelium, ascospores and ballistospore formation. The invention also discloses a method for preparing trehalose by using red yeast 2-14. The trehalose yield of the strain of the invention is high, the culture medium and the culture process are simple, and the extraction process is energy-saving and environment-friendly. The trehalose production method has the advantages of simplicity, practicability and low cost, and is easy to be popularized and applied in industrial production.
【技术实现步骤摘要】
本专利技术涉及一种微生物,特别是来自海洋的红酵母2-14OWoWorWa sp. 2-14) CGMCC NO. 4445 (已于2010年12月08日保藏在中国微生物菌种保藏管理委员会普通微生物中心CGMCC,保藏编号为CGMCC NO. 4445);本专利技术还涉及利用该菌株产海藻糖的方法。
技术介绍
海藻糖由两分子的吡喃葡萄糖单体以α-1,1糖苷键连接而成,其化学名为 α -D-吡喃葡萄糖基-α -D-吡喃葡萄糖苷,分子式为C12H22O11CH2O,相对分子量为378. 33 (含两分子结晶水),比旋光度D =+178° (20°C),熔点为97°C,加热会失去结晶水。由于其分子结构对称,无半缩醛基,所以既无还原性,也无变旋光性。其结构式为权利要求1.一种红酵母 2-14 0 oi/oiorWa 5/7. 2-14) CGMCC NO. 4445。2.根据权利要求1所述的红酵母2-14sp. 2-14) CGMCC NO. 4445,其特征在于,该菌株具有以下特征(1)形态特征细胞呈圆形或椭圆形,其大小4.5^5. 1X6. 3^7. 2 μ m,繁殖方 ...
