摘要:D-核酮糖和 L-岩藻糖是具有潜在价值的稀有糖,可用于农业和医药行业的抗癌和抗病毒药物.这些稀有糖通常通过化学方法生产,通常价格昂贵,复杂且不能满足日益增长的需求.此外,由于生物催化剂的短缺,用于生产 D-核酮糖和 L-岩藻糖的细菌来源的 D-阿拉伯糖和 L-岩藻糖通过 D-阿拉伯糖异构化和 L-岩藻糖的 D-阿拉伯糖和 L-岩藻糖异构化尚未实现工业化,导致产量低,生产成本高.在这项研究中,对来自丰水产热单胞菌的热稳定 D-核酮糖和 L-岩藻糖生产 D-阿拉伯糖异构酶进行了表征.来自 T 的重组 D-阿拉伯糖异构酶.Toyohensis (Thto-Daiase) 使用his-Trap 亲和层析纯化为 66 Kda 的单条带.天然酶以分子量为 310 Kda 的同源四聚体形式存在,观测到 D-阿拉伯糖和 L-岩藻糖的比活性分别为 98.08 和 85.52 U Mg-1.热稳定的重组 Thto-Daiase

标 题:Process for manufacturing tagatose
发明人：BEADLE JAMES R; SAUNDERS JAMES P; WAJDA JR THOMAS J
权利人:BIOSPHERICS INC
摘要:A process is disclosed for the synthesis of D-tagatose by isomerizing a mixture containing D-galactose with a metal hydroxide in the presence of a catalyst at a relatively low temperature to form an intermediate metal hydroxide-D-tagatose complex, and then neutralizing the intermediate with acid to yield D-tagatose. The method is also suitable for the synthesis of L-tagatose from L-galactose, and for the recovery of pure tagatose from crude tagatose syrups. Whey, deproteinized whey, or lactose may be used as the raw material for the D-galactose. The lactose in such cases is hydrolyzed to D-galactose and D-glucose before the isomerization step.
