PREVIOUSLY, we detected kojibiose (2-O-α-D-glucopyranosyl-D-glucopyranose) in sake and its moromi and isolated it from a mixture of oligo-saccharides synthesized from maltose and glucose by the culture filtrates of Aspergillus oryzae 1, Asp. niger 2 and Schizosaccharomyces pombe 3. It was also isolated from hydrol4. Sato and Aso5 crystallized it as α- and β-octaacetates, and Matsuda6 and Haq and Whelan7 synthesized it chemically.
此前,我们在日本清酒及其酒粕中检测到了曲二糖(2-O-δ-±-
D-吡喃葡萄糖基-
D-吡喃葡萄糖),并从黑曲霉(Aspergillus oryzae)1、黑曲霉(Asp. niger)2 和红球菌(Schizosaccharomyces pombe)3 的培养滤液中从
麦芽糖和
葡萄糖合成的低聚糖混合物中分离出了曲二糖。它还从hydrol4.Sato 和 Aso5 将其结晶为δ-和δ-八
乙酸酯,Matsuda6 以及 Haq 和 Whelan7 用
化学方法合成了它。
