Three kinds of novel cyclic isomaltooligosaccharides were isolated from the culture broth of a strain of Bacillus sp. T-3040, which had been isolated from soil. They were identified as cycloisomalto-heptaose, -octaose, and -nonaose, respectively, on the basis of their mass spectra, proton nuclear magnetic resonance spectra, carbon nuclear magnetic resonance spectra, infrared spectra, reducing power, and results of enzymatic analysis using endo-dextranase and exo-dextranase. They also showed features similar to cyclodextrins upon high-pressure liquid chromatography analysis using an ODS column.
从一株从土壤中分离得到的芽孢杆菌属T-3040菌株的培养液中分离出三种新型环状异麦芽寡糖。基于它们的质谱、质子核磁共振谱、碳核磁共振谱、红外光谱、还原力以及使用内切葡聚糖酶和外切葡聚糖酶的酶分析结果，它们分别被鉴定为环异麦芽七糖、环异麦芽八糖和环异麦芽九糖。在使用ODS柱的高压液相色谱分析中，它们还表现出与环糊精相似的特征。
